1A. Ask a Question- Good questions come from careful observations. You make observations by using your senses to gather information. Sometimes you may use instruments, such as microscopes and telescopes, to extend the range of your senses. Questions beginning with what, why, how, and when are very important in focusing an investigation, and they often lead to a hypothesis. 1B. Form a Hypothesis- A hypothesis is a clear statement of what you expect the answer to your question to be. Your hypothesis will represent your best “educated guess” based on your observations and what you already know. A good hypothesis is testable.

1C. Test you Hypothesis- The most familiar way is to conduct a controlled experiment. A controlled experiment tests only one factor at a time. A controlled experiment has a control group and one or more experimental groups. All the factors for the control and experimental groups are the same except for one factor, which is called the variable. By changing only one factor, you can see the results of just that one change.

1D. Analyze the Results- After you have completed your experiments, made your observations, and collected your data, you must analyze all the information you have gathered. Tables and graphs are often used in this step to organize the data.

1E. Draw a Conclusion- Based on the analysis of your data, you should conclude whether or not your results support your hypothesis. If your hypothesis is supported, you (or others) might want to repeat the observations or experiments to verify your results. If your hypothesis is not supported by the data, you may have to check your procedure for errors. If you cannot draw a conclusion from your results, you may have to try the investigation again or carry out further observations or experiments.

1F.Communicate your Results- After any scientific investigation, you should report…...

You need to mention 5 or more activities where physics is used. Remember to follow the APA style and give references. Physics is used in so many ways that most people do not even realize that they are using it. Even a stay at home mom uses physics more than one would think. Daily activities that many people do include physics without thinking about it, such as driving a car, using a headrest in a car, walking and running, flushing the toilet, and washing and drying clothes. Driving a car has many different aspects of physics involved, but today only acceleration, speed, and velocity will be discussed. People talk in terms of physics everyday without even knowing that is what they are discussing. For example, “speed” limit, how quickly a car can “accelerate,” and when they add a direction, they are actually talking about the velocity of a vehicle because velocity has a magnitude and direction, not just magnitude. According to Barry Parker in Issac Newton School of Driving, “you are accelerating and decelerating most of the time when you take a trip through the busy streets of a city, either by stepping on the gas, braking, or turning the steering wheel.”......

...Leaning Tower of Pisa by which he showed that, contrary to Aristotle’s account, the speed of a falling object is independant of its mass. It is precisely this power — to overturn wrong ideas, even if though they have been believed true for centuries, and to suggest a more complete understanding — that makes experimentation so central to all of the sciences. This experimental focus was not the last development in the physics that we’ll be looking at, though it did help pave the way for it. This next and final (for our purposes) leap was due to Newton — using mathematics to describe physics. After that, classical mechanics was essentially complete, with “only” quite a few decades of improvements and polishing before the introduction of relativity and quantum mechanics. It is physics at this level, the state of the art of classical mechanics circa the mid 19th century, that we’ll be studying in this course. .

...but unfortunately, due to the power of the Catholic church in his native Italy, his work in astronomy was widely rejected by his countrymen. His contributions to physics also place him in the ranks of the greatest scientists of all time. Without Galileo’s contributions to astronomy, mathematics, and physics, we would lack many basic understandings of the universe and our world. Body Galileo Galilei was the son of a musician born in Pisa, Italy in 1564. He studied medicine, but his interests laid in mathematics and physics. At age twenty-five, he became a professor of mathematics at Pisa. In 1591, he moved to Padua and lived there for many years. During his time in Padua, he had a twelve-year long relationship with a Venetian woman named Marina Gamba. The couple never married, but they had three children, two daughters and one son. Later, he moved to Florence where he lived for the remainder of his life. He died in 1642, coincidentally, the year of Sir Isaac Newton’s birth (“Galileo, Galilei (1564 - 1642)”). Galileo’s discoveries contributing to the fields of astronomy are what he is most famous for though this was not his only field of study (picture of his telescope invention on page 6, picture 2 from Rosen). Less notable, though no less important than his astronomical work, are Galileo’s contributions to physics, in particular to the areas of optics and motion, and mathematics. He employed his knowledge of mathematics both as a professor and as means to provide proof......

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. • The green arrow is usually longer than the blue arrow • The green arrow always points in the direction that the ball is going. • The blue arrow initially points in the direction that the ball is going but it then switches to the opposite way. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? • The green vector represents velocity and the blue vector represents acceleration. • When velocity is constant the acceleration declines. When I moved the ball at a slow, constant rate, the blue vector would get shorter or disappear. 3) Try dragging the ball around and around in a circular path. What do you notice about the lengths and directions of the blue and green vectors? Describe their behavior in detail below. • The blue and green vectors remain at a 90° angle to each other and the green vector becomes shorter than the blue vector. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. ...

...Unit 8 Assignment 1 20. Because the magnetic force which deflects the electrons is defined by F = q * v x B (v x B is the cross product of the 2 vectors), so: The force vector would always be perpendicular to both the v and B vectors. Since the force is perpendicular to the electron's velocity vector, and thus the path of the electrons, the work done by the field on the electrons is 0, because W = F*d*cos(theta), and theta=90 degrees, therefore cos(theta)=0, and W=0 If W = 0 then there is no change in the kinetic energy of the electrons, thus their speed remains constant; the acceleration provided by the magnetic field was used only to change the direction. 31. Well, it depends upon the Sensitivity setting of the metal detector. As it is clear, the threshold value of the metal detector's sensitivity can be adjusted to suit various needs. so it is obviously set to discard small variations caused by a very small pieces of metal. 34. Yes, There is nothing seperately as a DC motor or DC generator. It is simply a DC machine. It acts either as a motor or a generator depending on the input. If the input is mechanical energy, the output is electrical : this is generator action If the input is electrical, the output is mechanical torque: this is motoring action 48. when you step up the voltage with transformers you lose current.

...Exercise 5A, Case 1 I can see I will need the following equations to help me solve the next few cases involving the power plant. V=IR P=IV P=I2R Where V represents Voltage drop, I represents Current, R represents Resistance, & P represents Power lost. This intro tells me that I will be using a plant voltage of 120V to solve the first cases. I can see that I’ll be predicting various voltage drops across a completed circuit, from a power plant to a house. Exercise 5A, Case 2 If nothing is hooked up in the house: 1.) What is the current through the supply wire? To solve this I go back to my equation, deciding to use I=V/R , but thinking back on the intro I see there is nothing hooked up in the house; therefore, there is no current. The answer is 0. 2.) What is the voltage drop along the supply wire? To solve you would use the equation V=IR, I is 0; therefore, the voltage drop will also be 0. 3.) What is the amount of power converted to thermal energy (Power loss)? To solve this one, P=IV, I and V are both 0; therefore no power is lost in this Case. My predicted answers were correct in this case. If there is nothing in the house, then no current is flowing through the wires. Exercise 5A, Case 3 Now I’m asked that if I’m using super conducting wires with 0 electrical resistance and we plug in a 100 Watt lamp inside the house: 1.) What is the current through the circuit? I=P/V (100 watts)/(120 volts)= 0.83 Amps 2.) What is the resistance of......

GROUP 5 2FMT Date Performed: August 27, 2015 Date Submitted: September 3, 2015 EXPERIMENT #1—The Vernier and Micrometer Caliper ABSTRACT In this experiment, the group used a Vernier and micrometer caliper to measure lengths, widths, depths and diameters of various objects. The Vernier and micrometer calipers’ accuracy aided the group to find the volume and density of the objects—namely the steel metal cube, washer and marble. They also used the triple beam balance to weigh the objects. The group compared the density values they computed to the standard value, and also computed for their results’ percentage error. In the end, the group concluded that the micrometer caliper is easier to use, and somehow more error-proof compared to the Vernier caliper. 1. Differentiate the Vernier and micrometer scales. The Vernier scale has the accuracy of 0.05 mm and the capacity of 155 mm. It has a slider, and is usually used for measuring inside and outside diameter, length and width as well as depth. Meanwhile, the micrometer caliper has the accuracy of 0.01mm and has a 26mm capacity. It has a rotary handle and is usually used for measuring diameters and width. 2. Draw the figure for the micrometer readings below. a. 3.86 mm b. 1.59 mm 3. State some of the errors...

...Introduction In this project questions relating to Thermal Physics and Kinetic theory will be discussed and also diagrams to further explain them will be attached. Section B of the Physics syllabus will be completed by the end of this project. Bibliography 1. Thermal energy transfer by: * Conduction is the flow of heat energy through materials and substances in direct contact with each other. A conductor is a material that permits heat energy to flow freely within it. The better the conductor the more rapidly heat will be transferred. Conduction takes place when heat is supplied to a substance, the particles in that substance gain more energy and vibrate more. These particles then bump into neighboring particles and some of their energy is transferred to them. This process continues and energy is eventually transferred from the hotter end to the colder end of the object. * Thermal convection is transferred from hot places to cold places by convection. Convection occurs when warmer areas of gas or liquid rises to cooler areas of that gas or liquid. The cooler gas or liquid replaces the warmer areas......

...This acceleration is usually represented with the symbol g. Physics students measure the acceleration due to gravity using a wide variety of timing methods. In this experiment, you will have the advantage of using a very precise timer connected to the calculator and a Photogate. The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. You will drop a piece of clear plastic with evenly spaced black bars on it, called a Picket Fence. As the Picket Fence passes through the Photogate, the LabPro or CBL 2 interface will measure the time from the leading edge of one bar blocking the beam until the leading edge of the next bar blocks the beam. This timing continues as all eight bars pass through the Photogate. From these measured times, the program will calculate the velocities and accelerations for this motion and graphs will be plotted.
