A stone is dropped from the roof of a house towards the ground. The kinetic energy of the stone will be maximum: |
|
Answer» Just before it TOUCHES the GROUND When an object reaches the ground it has its maximum value of kinetic energy just before touching the ground. Since kinetic energy + POTENTIAL energy= CONSTANT; so on REACHING ground the potential energy of an object becomes zero (0). The kinetic energy on reaching ground becomes maximum. |
