Purpose
The purpose of this experiment is to understand the different forms of energy as a ball is thrown into the air and falls back to the ground at rest. As well as comparing the potential energy, kinetic energy, and total energy to compare what happens when this ball is thrown and dropped. We will also measure the total energy to determine whether or not there is a change.

Background Concepts
Kinetic energy is the energy of an object in motion. If an object is at rest, it will have 0 joules of kinetic energy.
Potential energy is the energy of an object that is some distance above the ground, …show more content…

Measure and record the height and velocity of the ball at that time.
For each of the three points in your data table, calculate the Potential Energy (PE), Kinetic Energy (KE), and Total Energy (TE). Use the position of the Motion Detector as the zero of your gravitational potential energy.
How well does this part of the experiment show conservation of energy? Explain.
It does not show the conservation very well because the total energy changes throughout the experiment, varying from after the release, at the top of the path, to before the catch. It does this due to the gaining or releasing of energy throughout the experiment.
Calculate the ball's kinetic and potential energy.
Logger Pro can graph the ball’s kinetic energy according to KE =12mv2 if you supply the ball’s mass. To do this, adjust the mass parameter.
Logger Pro can also calculate the ball’s potential energy according to PE = mgh. Here m is the mass of the ball, g the free-fall acceleration, and h is the vertical height of the ball measured from the position of the Motion Detector. The same mass parameter will be used to finde …show more content…

Simple mistakes including, rounding calculations the the wrong number, forgetting to switch the motion sensor to the right calibration, tossing the ball from the wrong height, all things that could be easily avoided that even an experienced student could have made. Other major mistakes could have been using the wrong equations to calculate the potential and kinetic energy of the ball, using the wrong file for the experiment, or only dropping the ball and not tossing it. My group made some of the simple mistakes at first but we quickly rectified them and made a successful chart, graph, and
