Why Is A Person Hit Harder When He Falls On The Hard Floor Then The Heap Of Sand Or Cotton Give Reason?

Why is a person hit harder when he falls on the hard floor then the heap of sand or cotton give reason? When you fall on sand, it takes some time for you to come to rest as the sand particles move. But when you fall on hard floor, your momentum becomes zero suddenly. So the change in momentum takes more time in sand than in hard floor.

Why is a person hurt less when he falls on a spongy surface * 1 point force exerted by him is more no force is exerted by Him force exerted by him is less none of these?

a person is less hurt or negligebily hurt because sponge contains air pores which helps us. when we fall on spongy surface the air present in the surface removed by sponge so that we r less hurt.

Why is a person hit harder?

A person hit harder when he falls on a concrete floor than when he falls on a heap of sand from the same height because on a hard surface he is brought to rest in a very short time, so greater force comes into action and he is hit harder.

Why a person falling on a cemented floor gets injured?

Answer. When a person falls on a cemented floor, the rate of change of momentum is very high because the person is abruptly stopped i. Hence the person gets injured due to the application of a large force on his body by to the floor.

Why is a person likely to get more hurt when he falls on a concrete floor than on the sand?

A man falling on hard concrete road receives more injuries than the one falling on ploughed sand floor. 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 less when you fall on a softer surface?

Why does it hurt less when you fall on a softer surface? The softer surface increases the duration of the impact, thereby reducing the effect of the force. The softer surface decreases the duration of the impact, thereby reducing the effect of the force.


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

Answer : When a person hits on cemented floor he is brought to rest in a very short time as a result of which a greater force comes into action in a very small time whereas in case of sand if a person falls he takes an interval to come to rest and hence, less force comes into action.


When a person hits a stone his foot is injured Why?

Answer Expert Verified

This is due to conservation of momentum and due to Newtons third law of motion. When man hits a stone, the same amount of force that he/she hits the stone with is projected back to the foot (equal and opposite reaction due to action). This is what causes injury to the foot.


Is it safe to jump on sand rather than a cemented floor why?

Its safe to jump on sand rather than a cement floor because sand has a smooth surface in which it is safe to jump over but cement is very hard if jumped on it serious injuries may occur.


What happens if you fall concrete?

Unfortunately, falls onto concrete can be quite common. Knee injuries of varying severity often occur with these falls. After you get past the initial pain, it becomes important to closely monitor your progress over the next few days. Persistent or worsening pain may indicate a much more severe injury.


Do you jump higher on grass or concrete?

Simple Answer, Yes! If you are comparing jumping off concrete, grass, sand or even dirt then yes jumping off hardwood will more than likely give you the highest jump when compared to the other surfaces. What is this? Gymnasium hardwood floors are used and design to absorb the athlete's impact when running and jumping.


Why do we get hurt on jumping on a hard surface as compared to jumping on a soft surface like a muddy floor?

we get hurt on jumping on hard surface as compared to jumping on a soft surface like a sponge or a muddy floor because whole we jump on a hard surface the rate of change in momentum is less. Thus, we get hurt if we jump on a hard surface like cemented floor.


Why does falling on grass hurt less than falling on concrete?

Why does it hurt more to fall on concrete than grass? Smaller forces are easier on your legs and you prefer to land on soft grass. Momentum/impulse explanation: Whether you land on concrete or soft grass, your change in momentum will be identical.


Why is it safer to collide with a soft cushion than a hard surface answer using terms time and force and momentum?

It is better to collide with a soft object than a hard object because the soft object makes the time of the impact increase, which decreases the force you feel although the impact is the same.


Why do you prefer to land on soft grass physics explain please?

Newton's Second Law explanation:

Your acceleration on soft grass is smaller because the change in velocity occurred in a longer period of time. Smaller acceleration on grass requires a smaller force. Smaller forces are easier on your legs and you prefer to land on soft grass.


Why do we get less injury in a soiled floor as compare to a cemented floor?

Solution: When a person falling on a heap of sand then the person is not injured because sand is not hard. There is large space between the particles of sand. Therefore, force acting on the person during fall reduces but in case of cement , cement is hard and solid .


When a person falls from a certain height on a cemented floor the floor does not yield?

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 hitting a heavy stone hurt more than hitting a light stone?

When we kick a football due to it's light weight it moves and gives less recoil to us due to law of conservation momentum and when we kick a heavy stone it gives us more recoil to conserve momentum and has more inertia of rest , so we get hurt by kicking a stone.


What is inertia answer?

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed when no forces act upon them.


Why would your foot hurt if you were to kick a wall physics?

its almost no acceleration. But when we kick the brick quickly we apply a lot of acceleration on it so the force increases, by newton's third law "every action has an equal and opposite reaction", the brick also applies the same force on our foot and we get hurt.


Why do you think the sand pit or the straw bed actually do to keep the athlete safe?

Athlete is made to land on the sand after long jump so as to increase the time of impact. This reduces the momentum and force by which he is landing on the ground. Thus, athlete is saved from getting injured.


Why does an athlete run before taking a jump?

The faster the velocity of an athlete the higher the jump he makes. Jumping after running for a certain distance covers more length than that of jumping without running. An athlete runs a certain distance before taking a long jump to gain the momentum that would help him/her to cover a longer distance.


Why does an athlete put some sand or cushion on the ground while jumping also state the law involved?

In a high jump athletic event, the athletes are made to fall either on a cushioned bed or sand bed. This is to increase the time of the athlete's fall to stop after making the jump. This decreases the rate of change of momentum and hence, the force.


What happens to a body after a fall?

Depending on how quickly your fall occurs, your body releases a surge of adrenaline when you first start to lose control and you begin to panic. Once the fall is underway, your body braces for impact by tensing your muscles and extending your arms or legs.


What should you look for after a fall?

Symptoms of a Potential Fall Injury

  • Severe or lingering pain.
  • Headaches.
  • Obvious swelling.
  • Ringing in the ears.
  • Bruising.
  • Loss of balance.
  • Dizziness.
  • Back pain.
