In a lab investigation, a group of students measures the speed of a 0.1-kilogram car at 0.80 m/sec at the bottom of a hill. The car’s starting position at the top of the hill is one-meter high. What is the potential energy of the car at the beginning of the experiment before its speed is measured? Calculate the kinetic energy of the car using the speed and mass values above. KE =

Does the potential energy at the top of the hill equal the kinetic energy at the bottom of the hill? If not, where did the energy go?
The potential energy at the top of the hill
