Physics
A stone is dropped from the roof of a house towards the ground. The kinetic energy of the stone will be maximum:
Just after it is dropped
When it is just on the half-way
Just before it touches the ground
When it touches the ground
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.
