The mass of the tennis ball is 0.05652 kg and the height is 0.374 on desk and 1.52 m on head. The potential energy is the same and the kinetic energy if 0.33 J for the deal and 0.977 J for the on a group member's head. The mass of a golf ball is 0.04564 kg and the height is the same as above. the For the golf ball my potential energy is larger than the kinetic, but for the tennis ball the kinetic energy is larger. Is that okay? When solving the velocity should I use the average of all my trials or the time that I solve for in the equation (d=1/2gt^2). Can you help check my work on the front side? Can you sketch a graph with 4 different lines of the potential and kinetic energy of the golf ball and the kinetic and potential energy for the tennis ball? The drop height is the x axis and the potential and kinetic are the y values (one on each side). Lastly, can you sketch a graph that shows how the energy transfers from potential to kinetic energy as the balm falls from the top of a building. Draw and label three lines (kinetic, potential, and total mechanic energy)

Potential Energy (J) Drop Height (m) NALYSIS: Answer these questions on a separate sheet of paper and 1. When was the potential energy the highest in this experiment and why? 2. When was the kinetic energy the highest in this experiment and why? 3. In theory, the potential energy at the top of the drop should match the kineti for each trial. Did all of the potential energy transfer to kinetic energy in you lost/ gained any energy? Explain using the law of conservation of energy. 4. Was this experiment perfect? Explain some possible sources of error. 5. Which has a greater effect on the kinetic energy of an object.. .mass or velocit 6. Would the golf ball have more or less potential energy on the moon than it d 7. Sketch a graph that shows how the energy transfers from potential to kinetic a building.
