It isn't. Kinetic energy is 1/2 x mass x speed squared, so if an object has mass, and it moves, it follows that it has kinetic energy.
It is called vaporization, and it happens because the water vapor is taking away some of the heat in the form of energy, and so the surface has less heat energy.
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
turns into vibration and heat energy.
Thermal energy is generated by the friction with the air (air resistance), it does not depend on the mass but the surface area of a falling object.
well, it gwets hot

Most of the light's energy gets converted into heat.
Energy from the sun that is absorbed by the Earth's surface is reflected back into the atmosphere or absorbed by land and water and transformed into heat.

gravitational energy is the same as potential and kinetic energy. When the ball is further from the surface of the earth it will have the most potential energy and when the ball gets closer to the surface of the earth that potential energy turns into kinetic energy because it is being used to move the ball towards the surface.
As the apple falls, its potential energy decreases while its kinetic energy increases, until it lands, at which point it has maximum potential energy.
Most of it is reflected back into space.
