A lead ball with a certain velocity is made to strike a wall, it falls down, but rubber ball of same mass and with same velocity strikes the same wall, it rebounds. Select the correct reason from the following:
-
If P is the force acting on the body, m is the mass of the body and a is the acceleration of the body, then according to Newton's second law of motion,
-
If the resultant of a number of forces acting on a body is zero, then the body will not be in equilibrium.
-
The friction experienced by a body, when at rest, is known as
