Energy of a Tossed Ball In this experiment, we will study energy changes using a Motion Detector. OBJECTIVES: • Measure the change in the kinetic and potential energies as a ball moves in free fall. • See how the total energy of the ball changes during free fall. MATERIALS: Computer Lab Pro Logger Pro Vernier Motion Detector Basketball PRELIMINARY QUESTIONS (PHY2048): For each question, consider the free-fall portion of the motion of a ball tossed straight upward, starting just as...

Based on your results. did all of the initial gravitational potential energy convert into kinetic energy? If there is a difference between the gravitational potential energy and the kinetic energy, what do you think caused the difference? Did the angle of the track or the mass of the cart have any effect on the data? Explain What were the sources of error m this experiment? How did your hypothesis compare to your conclusion?

The figure is a graph of the gravitational potential energy and
kinetic energy of a 70 g yo-yo as it moves up and down on its
string. The acceleration of gravity is 9.81 m/s2 .
a) By what amount does the mechanical energy of the yo-yo change
after 6.0 s? Answer in units of J.
b) What is the speed of the yo-yo after 4.5 s? Answer in units of
m/s.
c) What is the maximum height of the yo-yo?...

Determine values for translational kinetic energy, gravitational potential energy, elastic potential energy, and total energy at 0 m, 0.2 m, and 0.4 m above the release point for a 2 kg object pulled 0.2 m downward from the equilibrium position and released from rest while attached to the end of a vertical spring with k = 50 N/m. Be aware that the spring is stretched at the release position and at the equilibrium position so you will have to use...

If we examine a steel ball bearing falling through a vertical distance of a few feet (a situation in which the effects of air resistance on the motion of the object can be ignored), we find that the kinetic energy of the ball bearing is increasing. This is not a violation of the law of conservation of energy because the: The gravitational potential energy of the ball decreases as it falls. The gravitational potential energy of the ball increases as...

1. Is it possible for a system to have negative gravitational potential energy? a) Yes, as long as the kinetic energy is positive. b) Yes, as long as the total energy is positive. c) Yes, since the choice of zero of gravitational potential energy is arbitrary. d) No, because the kinetic energy of a system must equal its gravitational potential energy. e) No, because you can't have negative energy. 2. In an isolated system, for which of the following types...
