An engineering student is gathering data on the motion of a model car traveling down a ramp. If energy is conserved, the
potential energy of the car at the top of the ramp should equal the kinetic energy of the car at the bottom of the ramp. After
the first trial, the student calculates that the kinetic energy at the bottom of the ramp is less than the potential energy at the
top of the ramp. Which of the following can best explain this difference?
A. The student did not measure the increase in velocity.
B. The measured mass of the car was greater than the actual mass.
C. The measured height of the ramp was greater than the actual heig
D. The student did not include the loss of heat energy.
