Kinetic Energy Lab

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

Introduction: Chemical reactions are dependent upon two factors: temperature and concentrations of substance. We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction:

The lab five B was about friction and how its always present. The purpose of this lab wat to explore how friction affect motion. There are three types of friction we discuss like air, rolling, and siding.

A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x

Light passed through a transmission grating is often sent in all directions due to interference. The grating acts as a new wave source and causes the light to travel in different paths. Equation 1 below shows the relationship between path difference and light direction due to constructive interference. D represents the line spacing and sinƟ=a/c according to the drawing below.

In this activity, the marbles represent the narrow beam of alpha particles used to determine the structure of atoms, the unknown object represents the atoms that Rutherford studied, the cardboard represents the gold foil that was made up of gold atoms and the paper represents the approximate path that the alpha particles bounced off of or went through the gold foil at that Rutherford observed.

In chemical reactions bonds must be broken and new bonds must be formed. In order for this to occur the bonds must be made less stable. For bonds to become less stable a small input of energy is required and this is

Most organisms rely on enzymes to digest their food. In all reactions, there is an activation energy barrier. During digestion, foods must be broken down quickly so that the organism can get the nutrients it needs. In order for the food to be broken down, the activation barrier must be lowered. Without enzymes, many organisms would no longer be able to obtain the nutrients and energy they need to live. In this experiment, the goal was to understand how and why enzymes work in such specific ways, and to discover how enzymes function under different conditions.

Not all reactant particles have the same kinetic energy at the same temperature. At a higher temperature, there are greater proportions of molecules that have kinetic energy more than activation energy.

Overall, there were little to no complications for this experiment. There were modifications made to the first part of this lab, the student written portion. One change was the distances. In the original written procedure, see Attachment 02 of this report, the distances for all parts were noted as; next to the heat source, 5 inches away, and 10 inches away. After testing these measurements in the lab, the distances were alter to be next to, 2 inches away, and 5 inches away. This was done in order to produce more prominent temperature results. The distances for the 10 precision measurements were also modified. Originally the student was to take measurements for 80 seconds, starting at 2 inches away from the heat

The purpose of this lab was to be able to identify the factors that contribute in allowing carbon dioxide to exist as a solid, liquid, and gas. By performing this experiment, we were able to have a better understanding of the three phases being in equilibrium with each other. In its natural state, carbon dioxide exists as a solid. In order to exist as a liquid, the pressure required to make this phase change must be at minimum 5.11 atm. Once the solid carbon dioxide melts, the triple point is achieved through the energy that was absorbed. This point demonstrates that the three phases are now in equilibrium with one another. This experiment allowed us to determine that both pressure and temperature helped carbon dioxide exist as a solid, liquid, and a gas.

1: Gather all the materials needed for the experiment (a meter tape, a ramp, 2 carts with wheels and without wheels, a rubbermat, 5-gram masses, tape, a triple beam balance, a calculator, and 2 other people to help you [Person 1 and Person 2]).

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

The purpose of the lab is to find a projectile’s horizontal velocity and make comparisons of the effects of different inclined planes with the projectile of a ball.
