What is kinetic energy

Kinetic energy is the energy that an object has due to its motion or movement. For instance if a car drives into a wall the energy of its movement is what destroys the wall, That energy is kinetic energy.

Note: Heat is also a form of Kinetic energy because heat is the movement (vibration energy) of atoms or molecules.

What is the law of conservation of matter
Cannot Be Created or Destroyed.The law of conservation of matter states that matter is not created nor destroyed in any chemical or physical change.

however, this law doesn't apply to nuclear reactions because some matter is turned into energy.

What is gravitational potential energy

Gravitational potential energy is the potential energy an object has due to its position in a gravitational field. The higher an object is the greater its gravitational potential. When it falls the gravitational potential becomes kinetic energy.

Energy stored in height differences ~APEX

What is chemical potential energy

It is another form of potential stored in food, batteries, and fuel.
