cool

motion

The state in which one object’s distance from another is changing.

kinetic energy

Energy that an object has due to its motion.

potential energy

The energy an object has because of its position; also the internal stored energy of an object, such as energy stored in chemical bonds.

law of conservation of energy

The rule that energy cannot be created or destroyed.

force

A push or pull exerted on an object.

work

Force exerted on an object that causes it to move.

power

The rate at which one form of energy is transformed into another.

elastic potential energy

The energy of stretched or compressed objects.

gravitational potential energy

Potential energy that depends on the height of an object.

mechanical energy

Kinetic or potential energy associated with the motion or position of an object.

nuclear energy

The potential energy stored in the nucleus of an atom.

thermal energy

The total kinetic and potential energy of all the particles of an object.

chemical energy

A form of potential energy that is stored in chemical bonds between atoms.
