Bouncing A Ball
There are many types of balls in all different sizes and shapes; when these are made from some sort of natural or synthetic material and contain air or some other form of gas, they have the ability to use elastic energy to return to their original shape after being bounced, hit or squashed.
This 'elastic energy' only comes into action when the ball comes in to some sort of impact with another object such as a floor. In this case it makes sense that the higher the ball is positioned in the air before it is dropped, the higher the return bounce will be after hitting the floor.
This is because a tennis ball while in the air always starts with gravitational potential energy, when the ball is dropped this GPE forces it to move towards the earth. While doing so this energy is transferred into kinetic energy as it's moving through the air.
When the ball hits the ground this kinetic energy is turned into elastic energy while at the same time also creating many other forms of energy such as sound, heat or friction. There is also a certain amount lost to the surface of which the ball is impacting with.
All of this lost energy after the ball has gone through all of these energy transfers is the reason why the ball never reaches the height you started with before you dropped the ball; and the distance between this height and the height after the ball has bounced, accounts for all the lost energy in the process of dropping the ball.
However this returning height can be changed by giving the ball a higher starting point in the first place. This gives the ball a higher GPE which will give every other type of energy this is transferred into an increased rate. This will ultimately force the bounce height of the ball higher than if it was dropped at a lower height.
Therefore, as the drop-height increases, the bounce-height too will increase, but not always in direct proportion. The efficiency will decrease as the drop height is increased.
This is called the coefficient of restitution.

∙ 10y agoThe reason why footballs bounce when they fall to the ground is due to gravity and energy. Gravity is the pull of the earth and energy is the amount of force exerted. When the ball falls, the ball gains energy which needs to be exerted. The energy is propelled by counteracting the fall so the ball will bounce until the energy is depleted.

∙ 14y agoIt will bounce up again.
one can also say that the ball itself stands still, and when the floor hits it the floor will bounce away again.
It depends on ones perspective.
Normally we say that the larger of the two objects stands still.
In any case will the two objects exchange and absorb some energy.

∙ 12y agoGravity has a little effect on it. However the main force stopping the ball rolling is the friction force of the floor. The ball will stop rolling when the velocity of the ball is the sames as the velocity of friction force.

Why does a ball come to stop when it is rolled across the floor?
Because of the forces that act on the ball in the direction opposite to its motion ... air resistance and friction with the floor.
If you roll a ball down a hill will the ball eventually stop by its own?
Yes.
Why is energy lost during bouncing?
A lot of things happen when an object bounces. Some of the objects energy, or momentum, goes into the floor which causes the surrounding floor to warm up slightly. Also, there is inefficiency that will cause the ball to eventually stop bouncing. Also, hearing the ball hit the floor means that energy went into the surrounding air molecules, causing them to heat up slightly as well as allowing you to hear the ball hit the floor. All of this causes energy to be lost in the bouncing.
How does finction cause a ball to slow down?
It does because when the ball hits the surface and the surface magnified would look rugged anyways when the ball hits the surface the friction pulls on the ball causind it to slow down and if you roll a brick down a hill you will find it will stop easier than a ball smooth surface
A soccer ball is rolling down a field At t0 the ball has in velocity of 4 ms If the acceleration of the ball is constant at -0.3 mss how long will it take the ball 2 come to a complete stop?
long enough
When you roll a ball acrossthe floor it comes to a stop because you are no longer exerting a force on it?
No. That statement is false, mainly because it is not true. When you roll a ball across the floor, it comes to a stop because the inevitable friction where the ball contacts the floor robs it of kinetic energy. If the friction could be eliminated, the ball would not come to a stop. No force is required to keep a moving object moving.

How could we use roll and role in a sentene?
In a fire drill we have to stop drop and roll.
Why do ball if you roll it will stop?
because of the friction.
If you roll a ball down a hill will the ball eventually stop by its own?
Yes.
What did one bowling ball say to the other bowling ball?
im gonna beat u rolling egghead r it said nothing because bowling balls cant talk
What to do if your pants are on fire?
Stop whatever you are doing, then lie on the floor and roll till the fire is out.
How do you make a ball roll slowly down a ramp?
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
How do you jump on super monkey ball step and roll?
stop playing child games!
When a ball is rolling on the floor and the fingers are used to stop it is work or force used?
Rolling the ball would be work and stopping the ball would be force.
A basketball rolls to a stop along a gym floor without anyone touching it why did this occur?
The ball rolled to a stop because the opposing force of friction stopped the ball. If the floor had been frictionless, it would have continued without stopping or even slowing.
