Question

A science teacher demonstrates the law of the conservation of energy using an object of mass 6.0-kg falling straight down from rest. He sets up a photogate at each of three points A, B, and C along the object's path to measure the travel time taken, and then he measures the appropriate distances.
Ignoring friction, when his students perform the calculations using the data, what should they find about the object's kinetic and gravitational potential energies?

A. Their sum is always less than the initial gravitational potential energy.

B. Their sum always exceeds the initial gravitational potential energy.

C. The sums at A, B, and C are always the same and equal to the initial gravitational potential energy.

D. The sums at A, B, and C are always different from one another and from the initial gravitational potential energy.


There's no diagram and I'm xonfused .
