Answer: (C) d
K.E = P.E loss = mgd
K.E is therefore proportional to d (distance)
Explanation:
According to the law of conservation of energy, which states that energy cannot be created nor destroyed in an isolated system.
Therefore, when an object drops from a certain height the potential energy of the object at that height is gradually convert to kinetic energy as it moves through distance d.
K.E = P.E loss = mgd
K.E is therefore proportional to d (distance)
