When a ball is dropped from a height of 10 m?

Answer Expert Verified When the ball is dropped from a 10m height, it loses 40\% energy thus affecting the same percentage of height when it bounces back. Now 40\% of the energy lost means 40\% of the height also lost on bouncing back. Given height is 10m and when you lose 40\% of 10m, left will be 60\% of 10m.

Is the energy of a ball falling from a height of 10 Metres is reduced by 40\% How high will it rebound?

Complete step by step answer: Hence the ball will bounce back to a height of 6m.

What happens to the total energy of a ball that is dropped from a height?

Energy cannot be created or destroyed, but can be transformed. If a ball drops, energy is transferred and transformed, in sound for instance, but the total amount of energy remains the same. Dropping the Ball: Before dropping a ball, you must lift it up from its resting surface.

What percentage of the initial potential energy was wasted as the ball was hitting the ground?

Just use the formula for potential energy, mgh. You don’t need to know the mass m. 40\% of the inital energy is lost in the impact to the ground, so the ball will have 60\% afterwards.

When a ball is dropped from a height there is decrease in it?

So the moment you drop a ball from a height, and till it reaches the ground, its PE energy decreases while its KE is increasing till it reaches the ground level, where its PE is zero while KE just before touching the ground is maximum.

What is unit of potential energy?

Potential energy is energy stored in matter. The joule (J) is the SI unit of energy and equals (kg×m2s2) ( kg × m 2 s 2 ) .

What is the difference between kinetic and potential energy?

Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. On the other hand, kinetic energy is the energy of an object or a system’s particles in motion.

How does the height you drop a ball from affect the percent energy lost when the ball bounces?

The final bounces lose energy to air resistance again. If the tennis ball is dropped from a larger height, the percentage of potential energy lost will be greater because the ball will fall a for a longer amount of time, which means it will lose more energy through air friction and from the larger impact of the ground.

What happens to a ball when it is dropped?

When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy. When the two balls are dropped at the same time, they hit each other (collide) just after they hit the ground, and a lot of the kinetic energy in the larger ball is transferred to the smaller ball.

What is the height of the ball when falling down?

Now while ball falls down it loosing 10\% of its energy due to air resistance so the total amount of energy at the ball just before collision is 90\%. At the collision it is loosing again 10\% of energy i.e. 10\% of 90 means 9\%. So the ball will bounce back with the 81\% of energy. So the ball should achieve the height of 8.1 meter.

How much energy does a ball lose when dropped from 10m?

A ball is dropped from a height of 10m. It loses 10 \% of its initial energy due to air resistance and 10\% when the ball comes in contact with the ground. Till what height will the ball bounce back again?

What is the amount of energy at the ball just before collision?

The ball falling from the height of 10 meters, means initially it is having 100 percent of energy due to its height. Now while ball falls down it loosing 10\% of its energy due to air resistance so the total amount of energy at the ball just before collision is 90\%.

What is the height of the ball at the collision point?

At the collision it is loosing again 10\% of energy i.e. 10\% of 90 means 9\%. So the ball will bounce back with the 81\% of energy. So the ball should achieve the height of 8.1 meter. But while bouncing back again due to air pressure the ball will loose its 10\% of total energ available i.e. 10\% of 81 means 8.1\%.
