What kinds of energy conversions are involved when a mass is falling eo the ground?
A. Power to work
B. Potential Energy to Kinetic Energy
C. Kinetic Energy to Potential Energy
D. Force to Kinetic energy
I think the answer is C, because the object is moving and then will ultimately hit the ground... KE to PE?
