The only answer that's true in any case is: When it's speed is greatest.
A free-falling object without air resistance continues to accelerate as long as it
falls, so its maximum speed occurs at the bottom of the fall, just before it hits the
ground, and we can be sure that that's also the instant of greatest kinetic energy.
But the rock is "bouncing", so we don't know how its speed may be changing.
The greatest speed may not be at the bottom of the mountain, so the best
we can say is that whenever and wherever during the tortuous trip it has the
greatest speed, that's also the moment of greatest kinetic energy.
What else can I help you with?
Kinetic energy is the energy of?
Motion.
Energy in the form of motion?
The energy of motion is called kinetic energy.
What are the two main forms of energy?
The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.
Which phase or state of matter has the most kinetic energy?
The physical state, or phase, that has the greatest kinetic energy is gas. In a gas, the molecules are more free to move and they move more rapidly than in the other phases, and it is this motion that constitutes kinetic energy.
When does the skier have the greatest potential energy?
Just standing there, a skier on the top of the mountain has potential energy. If she uses her poles to push-pull before taking off, she's building up a small amount of kinetic energy. If a skier is then moving down the mountain, his movement downward is kinetic energy which increases as his speed increases. If he or she collides with an immovable object while skiing, kinetic energy abruptly ends. If he or she takes off from the top of the mountain and an avalanche happens to hit at the same time, the kinetic energy of the avalanche engulfs the skier and overpowers the lower kinetic energy of the skier. The skier and avalanche become as if one in the kinetic force of the avalanche--until the skier collides with something or is buried, and thus is separated from the avalanche's kinetic energy which continues until the avalanche stops.
What energy is there when a ball bounces?
Basically 2 types of energy are involved, Kinetic and Potential energy. When the ball bounces the kinetic energy starts changing into potential energy or as commonly referred to as energy of recoil.
What the kinetic potential energy conversion that occur when basketball bounces?
When a basketball bounces, the potential energy is converted into kinetic energy as it falls downward. This kinetic energy then allows the ball to compress upon impact with the floor, storing elastic potential energy. This potential energy is then converted back into kinetic energy as the ball rebounds back up.
Why does a ball gets lower and lower when it bounces'?
The greater the gravitational potential energy the more the kinetic energy, so as it bounces, the gravitational potential energy will decrease, so will the kinetic energy decrease and everything will decrease and they will suck
Is kinetic energy destroyed when you catch a ball in the air before it bounces?
No
When is the the kinetic energy the greatest?
The kinetic energy of an object is greatest when its velocity is at its maximum. Kinetic energy is directly proportional to the square of the velocity of the object, so as the velocity increases, the kinetic energy increases exponentially.
When does a skydiver have the greatest kinetic energy?
A skydiver have the greatest kinetic energy as he/she wants to hit the water.
What energy changes occur each time a ball is dropped and bounced?
When a ball is dropped and bounces, potential energy is converted into kinetic energy as it falls. Upon impact with the ground, some of the kinetic energy is converted into elastic potential energy as the ball compresses. This elastic potential energy is then converted back into kinetic energy as the ball bounces back up.
When is kinetic energy greatest?
Kinetic energy is greatest when an object is moving at its fastest velocity. This is because kinetic energy is directly proportional to the square of the velocity of an object, so as the object's speed increases, its kinetic energy increases exponentially.
What is the following molecules in order from least kinetic energy to greatest?
The molecules with the least kinetic energy are in solid form, followed by liquid, and then gas with the greatest kinetic energy.
What has the greatest amount of kinetic energy?
Kinetic energy = one-half the product of an object's massand the square of its speed.So, the object with the greatest product of (mass) x (speed)2 has the greatest kinetic energy.
What happens to the kinetic energy of the ball after its collision with the ground?
The kinetic energy of the ball is transferred into other forms of energy, such as sound, heat, and compression. Some of the energy may also remain as kinetic energy if the ball bounces back up.
How does kinetic energy of the ball relate to the bounce of the ball?
kinetic energy is enegy being used, the opposite of potential energy, which is energy being stored, or waiting to be used. When a ball bounces it is using its energy. When a ball is held by a person, it holds potential energy, or the potential to use energy.
