Question

CLASS 9

Assertion: You are hurt more when you fall on a cushion than on a hard floor.
Reason: Momentum change occurs over a shorter time interval on hitting a hard surface than on a soft cushion.

Answer 1

Answer:

The statement of the Assertion is false but the Reason is true.

Explanation:

Momentum: the force that makes something move faster and faster. Force is the rate of change of momentum. If the momentum decreases force will increases because they are inversely proportional to each other.

Assertion's Reason:

We get hurt faster when we fall on an hard floor than on a cushion because momentum on an hard floor goes less than zero before than the soft cushion and the cushion we get the enough momentum to get less hurting.
