Heat, sound and more kinetic energy as things are moved by the impact of the object.

What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
How Kinetic Energy is related to Potential Energy?
Potential and kinetic energy are sort of like inverses. They are not technically inverses strictly speaking in the mathematical sense. Potential energy can become kinetic energy, and vice versa. Keep in mind the mathematical concept of the change in each. (change in) Potential energy= (change in) Kinetic energy. For example, let's say that we had a mass of 1 kg suspended 1 metre above the ground. If we drop it, its kinetic energy by the time it hits the ground is (1/2)mv2 . (1/2)(1kg)(9.82 ) (m2 ) or 48.02J It's potential energy at this point is 0, because it is on the ground and is not suspended in the air. Potential and kinetic energies act as inverses because before the mass was dropped its kinetic energy was 0 and its potential energy was 48.02J. By the time the mass had dropped to the ground however, the potential energy had all transferred into kinetic energy.
How does potential and kinetic energy relate to football?
The football has (gravitational) potential energy because of its position above the ground. It also has kinetic energy because it is moving. The combined energy is called mechanical energy.
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
Can you have maximum gravitational potential energy and maximum gravitational kinetic energy at the same point?
No, gravitational portential energy is more with more hight and gravitational kinetic energy is maximum just before reaching the ground.
What happen to the kinetic energy of a falling book when the book hits the floor?
when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.
What is an example of energy flow?
Tide = Flow of kinetic energy from higher ground to lower ground Wind = Flow of kinetic energy from higher pressure to lower pressure Electricity = Flow of electrical energy (transfer of kinetic energy) from higher voltage to ground or low voltage.

What is the kinetic energy of the free falling object that eventually stop on reaching the ground?
Once the object has reached the ground, its kinetic energy is zero.
Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
When is potential energy transformed into kinetic energy?
As soon as the object is allowed to move, potential energy starts getting transformed into kinetic energy. For example the object placed on height. As soon as it is allowed to fall, the potential energy starts getting converted into kinetic energy. It is maximum at the time the object touches the ground.
What type of energy is a curve ball is it kinetic?
Basically, if it moves, it has kinetic energy. And if it is above ground level, it has gravitational potential energy.
Can an object have both potential and kinetic energy at the same?
Yes. Example: A ball thrown directly upwards; at any moment (except at its maximum height) it has velocity, and therefore kinetic energy. Also, at any moment (except when it touches the floor) it has gravitational potential energy (assuming you use the ground level as reference level).

When you hold a ball above ground does it have kinetic energy?
Potential, changing to kinetic when you release it and it falls.
