Work/Energy Question

Question

An object is dropped from rest from a certain height. Air resistance is negligible. After falling a distance d, the object's kinetic energy is proportional to which the following?

(A) 1/d^2

(B) 1/d

(C) sqrt (d)

(D) d

(Thanks)

Answer 1

The object's kinetic energy is proportional to d.

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. = Potential energy loss = mgd

Thank you so much :) makes a lot more sense
