What happens to the energy of a ball that is dropped from a 5ft table?

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.

What would the kinetic energy be for the 5 kg ball traveling at?

KE=12mv2=12(5)(12.5)2=390.625 Joules.

What happens to the energy of a ball as it is dropped from a height of 10 m?

The potential energy decreases and the kinetic energy increases during the fall.

How does the height from which I drop a ball affect the height of the initial bounce?

If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.

What is the kinetic energy of 5 kg?

The equation for kinetic energy is ½mv2, where m is your mass and v is your velocity. So for the given information, we have KE = ½(5 kg)(72) =122.5 Joules.

How much kinetic energy does a 5 kg mass have if it is traveling at a speed of 10 m s?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

When a ball is dropped from a height to the ground what is happening to the total mechanical energy during the entire fall?

The total amount of mechanical energy is conserved in free-fall situations (no external forces doing work). Thus, the potential energy that is lost is transformed into kinetic energy. The object loses 200 J of potential energy (PE loss = m * g * h where the m•g is 200 N (i.e., the object’s weight).

When a ball is dropped at a certain height its gravitational potential energy?

When the ball falls, some of its gravitational potential energy is converted to other forms of energy, such as kinetic energy and rotational energy. When it rebounds, these other forms of energy is converted back to gravitational potential energy.

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 the gravitational potential energy when a ball is dropped?

The gravitational potential energy is converted to kinetic energy. Gravitational potential energy at the top = kinetic energy at the bottom A ball of mass 0.4 kg is lifted to a height of 2.5 m. It is then dropped, from rest. The ball returns to the ground with a speed of 7.1 m/s.

What is the kinetic energy of the ball at 5m height?

It can be solved using work energy theorem!!! At the height of 5 m, K.E is 0 J and potential as mgh=5*5*10=250 J. Hence at lowest height, the Potential energy should be converted into the kinetic. Hence, the KE of the ball should be 250 J just before touching the ground.

What is the speed at which a 50 kg object falls?

The 50 kg mass returns to the ground with a speed of 20 m/s, which is exactly the same as the speed of the 25 kg mass. If there was no air resistance or drag, the 25 kg mass and the 50 kg would fall at the same rate of 10 m/s 2. Dropped from the same height, they both hit the ground at the same speed and after the same period of time.

What is the initial velocity of a ball dropped from rest?

If the same body is thrown upward at an angle, and air resistance is negligible, its acceleration will be downward and equal to 9.8 m/s2. After 1 second, a ball dropped from rest will have fallen 4.9 m. A ball is projected straight up with an initial velocity of 20 m/s. After 3 seconds its velocity will be -9.4 m/s.
