Question: What Energy Possessed By The Bouncing Ball Before And After It Fell To The Ground?

Is momentum conserved when a ball bounces?

conservation of momentum: The amount of momentum in a system remains the same after a collision.

elastic collision: A collision in which all of the momentum is conserved.

For example, a ball that bounces back up to its original height.

For example, a ball that only bounces partially to its original height..

Where does the energy of the ball go each time it hits the ground answer in detail?

When the ball collides with the floor, some of this kinetic energy is transferred to the floor and converted to thermal energy (friction) and elastic potential energy (ball deformation.) Some of the kinetic energy is also transferred to sound energy, in the ―boing‖ noise we hear during the collision.

How does starting height affect an object’s energy?

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

Why was it important to drop the ball from the same height three times?

Answer: It is important to do this to test your theory multiple times, so that you can see what effect the drop has on it when doing this multiple times. The numbers were slightly different because the recordings will not always be the same.

What happened to the lost energy?

As all of the answers say: Energy cannot be “lost”. … This means that, whatever happens you will “lose” some energy in the form of heat. This energy is unusable again. Sure, you can take some of the energy of the sun and convert it into electricity, but however, we’re able to take in only a small fraction of the energy.

What happens to the potential energy of a body when dropped from certain height?

During its fall, its height from the ground reduces and gains speed. So, its potential energy decreases with a corresponding increase in kinetic energy. Just before it reaches the ground, the ball has zero potential energy and maximum kinetic energy.

Why does the height of a bouncing ball decreases?

Since the height to which the ball will bounce is directly proportional to its energy (barring effects of air friction), with a coefficient of restitution of less than one the ball will bounce less and less high. When the ball hits the floor, its center of mass needs to be decelerated.

What has caused the ball to make a deeper dent?

Answer. Explanation: the reason being for deepest bend is the h of the ball is directly proportional to the depression…more the h deeper the depression.

How does a surface affect the bounce height of a ball?

A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. The more energy absorbed by the surface, the less that remains in the ball for it to bounce.

What happens to the energy of the ball when the ball stops bouncing?

If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. … This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely. The energy has left the ball!

What type of ball bounces the highest?

rubber ballExplanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.

What is the relationship between drop height and bounce height?

The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.

How does the drop height of a tennis ball affect the bounce height?

That height fraction is equal to the fraction of energy that the ball successfully stored and returned during its bounce. … When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.

How is momentum conserved when a ball bounces off a wall?

Figure 52: A ball bouncing off a wall. Clearly, the momentum of the ball is changed by the collision with the wall, since the direction of the ball’s velocity is reversed. … It follows that the wall must exert a force on the ball, since force is the rate of change of momentum.

What type of energy does a ball have before it is dropped?

potential energyLifting a ball into the air before dropping it gives it a type of energy called ‘potential energy’ – which means the ball has the potential to do some work. When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy.

Is energy conserved when a ball bounces?

The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor.

Do heavier balls bounce higher?

So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher. … If there’s a little difference between them, that can affect how much energy gets lost in internal friction as the ball flexes during the bounce itself.
