If you jump barefooted on a hard surface, your legs get injured. But they are not injured if you jump on a soft surface like sand or pillow. Explain.

Answer :

When we jump barefooted on a hard surface change in momentum occurs in a very small time so the force exerted by body is maximum and we get hurt. While in case of soft surface the change in momentum occurs in suitable amount of time, thus we don’t get hurt.
