Why does the person falling on the cemented floor get injured but not the person falling on a heap of sand?

When a person falls on a cemented floor, the rate of change of momentum is very high because the person is abruptly stopped i. So the change in momentum takes place at longer interval of time. Hence a small force is exerted on the body of the person when he falls on a heap of sand. Therefore, he does not get injured.

Why does a fall on a hard concrete floor hurt more than a fall on a sand surface?

Answer: When you jump onto the concrete surface, your feet are brought to rest almost instantaneously because the rate of change of momentum is very high. Hence, you get injured due to a large force on your body on account of the hard floor.

Why does it hurt more to fall on a concrete than on ground?

Explanation: Because concrete is harder than ground. That is why it hurts more when you fall on concrete than ground.

When a person falls from a certain height on a cemented floor?

When a man falls on a hard cemented floor his momentum reduced to zero in a very short time and hurt the man. Whereas when a man falls on a heap of sand. As sand can compress, it takes longer time for the man to hit the ground (or hard surface).

Why does a person jumping from a height on a cemented floor gets more injury than when he jumps on a heap of sand?

ii) A person jumping from a height on a cemented floor gets injury than when he jumps on a heap of sand: When a person jumps on a cemented floor, the momentum of the person reduces to zero in a very small interval of time and so the floor exerts a large force on his feet. Hence the person gets injured.

Why does a person jumping from a height on a cemented floor get more injury than when he jumps on a heap of sand?

Why is falling onto a pile of leaves more comfortable than falling onto a hard concrete floor physics?

Why is falling onto a pile of leaves more comfortable than falling onto a hard concrete floor momentum? Falling into a leaf pile is much more comfortable than falling onto the bare ground. It takes more time to come to rest falling in a leaf pile, so the stopping force is less.

What happens to water when it falls on cemented ground?

Answer: The water does not seep down the cemented floor because, when the floor is cemented, the surface is made out to be smooth and non-porous, that is why the water remains above the surface and does not sink into the ground through the cement.

When a person falls from certain height on cemented floor he receives more injuries Why?

Laws of Motion A concrete floor is hard and it does not yield. Therefore, man falling on concrete floor is stopped abruptly in a short interval of time and suffers a sudden change in momentum. Therefore, concrete floor exerts a large force and man gets more injury.

Why does it hurt when you fall on a concrete floor than on a wooden floor?

A concrete floor “gives”less than a wooden floor. Both floors provide the same impulse – the amount of force needed to bring your body to zero. If contact time is less for a concrete floor, the amount of force exerted must be greater to give the same impulse.
