Question

When you jump on a concrete surface, your feet hurt
more than when you jump on sand. Explain on the
basis of Newton's laws.​

Answer 1

Answer:

space between the sand particles

Explanation:

the friction among sand and concrete

Answer 2

Explanation:

When we jump on sand most of our Kinetic energy is transferred to the sand. And according to Newton's third law we get less reaction force on ourselves.

But when we jump on sand not much of the energy is absorbed and we get more reaction force on ourselves.

That's why it hurts more on concrete.
