kinetic energyThe energy of motion is kinetic energy.
it never runs out
First, energy sources are usually split into kinetic and potential. Kinetic energy is the energy of something in motion: the earth in orbit about the sun has kinetic energy. The earth also has kinetic energy due to its rotation. The moon orbiting the earth has kinetic energy, but the moon does not rotate. A car zipping along the highway has kinetic energy as does a train moving on a track. Potential energy is something which can become energy. A rock resting on top of a building can fall off the edge and gravity will pull it downward faster and faster. We say it had potential energy on top of the building's gravity well and this became kinetic energy as it fell. When the rock strikes ground, its kinetic energy will convert to thermal energy warming it and the earth beneath it. Other forms of potential energy include water held by a dam, a gas which has been compressed, and chemicals which can react, such as chemical batteries.
Moving vehicles, such as cars and trains, utilize kinetic energy for their motion. Wind turbines convert the kinetic energy of moving air into electrical energy. Pendulum clocks rely on the kinetic energy of swinging pendulums to keep time. A bouncing ball demonstrates kinetic energy as it moves up and down. Roller coasters harness kinetic energy to propel riders along the track.
Energy in motion is called kinetic energy. It is the energy possessed by an object due to its motion.
Movement of any sort involves kinetic energy.
Kinetic and electric.
The object's kinetic energy is 2,500 joules.
One, Kinetic, with numerous sources...
The kinetic energy comes from potential energy, which he got from ATP energy, which is produced through food. Potential energy is converted to kinetic energy after the muscles contract and relax. Sources: School science
Energy doesnt run out, it is just transferred. For example, a ball in a high place is said to have potential kinetic energy, if it then falls that energy is transferred to kinetic and thermal energy. Upon rest, the ball again has potential kinetic energy.
kinetic energyThe energy of motion is kinetic energy.
Radiant energy from the sun, kinetic energy and heat from the decay of radioactive material in the Earth's interior.

As you will know energy can not be created. Only transferred from one thing from another. Solar energy captures energy from the sun. Wind energy gets it from the kinetic energy making it move. And hydro electric also gets from kinetic energy. But kinetic energy from the movement of the waves.
