Question

As a rock falls without air resistance, which of the following is true?. . A. The kinetic energy of the rock transforms into potential energy.. . B. All the potential energy becomes kinetic energy at the instant it is dropped.. . C. Part of the potential energy of the rock becomes kinetic energy during each part of the fall.. . D. The potential energy of the rock has been transformed into thermal energy by the time the rock reaches the ground.

Answer 1

Out of the choices given, the one that is true is part of the potential energy of the rock becomes kinetic energy during each part of the fall. The correct answer is C. 

Answer 2

Answer:The correct answer is option C.

Explanation:

The potential energy is defined the energy possessed by an object due to its position where as kinetic energy is defined as energy possessed by an object due to its motion.

Since, the energy remained conserved. So, when an objects falls down ,the potential energy of that objects starts getting converted into kinetic energy.

Hence, the correct answer is option C.
