Why do we use rubber ropes instead of steel cables when bungee jumping?
Bungee jumping cords, (and Vanuatuan vines, to a lesser degree) rely on the principle of elasticity to reduce the forces acting on the jumper. An elastic object is one, like a rubber band or spring, that is able to store energy when it is compressed or extended.
Why do gymnasts use very thick floor mats?
Q:Why do gymnasts use floor mats that are very thick SolutionStep 1 of 1Gymnasts use thick floor mats, because the more thicker the floor mat, the slower gymnast willhit the floor,reducing the impulse hence the impact. A thicker floor mat reduces impulse and it will help gymnasts to avoid injuries.
Why is more impulse delivered during a collision when bouncing occurs than during when it doesn t?
13. Why is more impulse delivered during a collision when bouncing occurs than during one when it doesn’t? momentum = momentum before and after the collision.
Why is it important to follow through when hitting a homerun?
Why is it important to “follow through” when trying to hit a homerun? maximizes time that the bat is in contact with the ball. increase amount of time it takes the person and therefore decreases force.
Why is the Pelton wheel and improvement?
Why is the Pelton Wheel an improvement over paddle wheels w/ flat blades? The curved paddle causes the incoming water to make a U-turn upon impact w/ the paddle. The water bounced, so the impulse increased.
Why is it disadvantageous to move into an oncoming punch?
Why is it disadvantageous to move into an oncoming punch? He should avoid moving into an oncoming punch because this would do the opposite and would make the impact of the punch take less time and so it would increase the amount of force that he feels.
Why should a boxer avoid moving into an oncoming punch?
He should avoid moving into an oncoming punch because this would do the opposite and would make the impact of the punch take less time and so it would increase the amount of force that he feels. force has an impulse.
When a dish falls will the impulse be less if it lands on a carpet than if it lands on a hard floor?
When a dish falls, will the impulse be less if it lands on a carpet than if it lands on a hard floor? No. The impulse would be the same for either surface because the same momentum change occurs for each. It is the force that is less for the impulse on the carpet because of the greater time of momentum change.
When a car is out of control is it better to hit a haystack or a concrete wall?
Although the momentum change and impulse are the same, the force is less when the time of momentum change is extended. Be careful to distinguish among force, impulse, and momentum. Examples: – When a car is out of control, it is better to hit a haystack than a concrete wall.
