Question
An apple breaks off from its branch and falls toward the ground 9 m below, accelerating all the way. At Point S the apple is 6 m from the ground. At Point T the apple is 3 m from the ground. How does the sum of the gravitational potential and kinetic energies of the apple compare between Point S and Point T?
A. The sum is greater at Point S than at Point T.
B. The sum is the same at both points (but greater than zero).
C. The sum is less at Point S than at Point T.
D. The sum is zero at both points.

Answer:
B
Explanation:
Conservation of energy applies to this. as the apple falls: goes from point S to T, the Potential gravitational energy reduces, but Kinetic energy increases at the same rates.
