The energy an object possesses due to its motion, increasing with its speed.

The energy stored in an object due to its temperature, increasing with its heat.

The energy an object possesses based on its position relative to a gravitational field, increasing with its height.

The energy stored in the bonds of molecules, released during chemical reactions.

The energy stored in an object when it is stretched or compressed, released when it returns to its original shape.

Energy transferred when an object moves due to a force, like pushing, pulling, stretching, or squashing.

Energy transferred when an electric charge moves through a potential difference, like current flowing in a circuit.

Energy transferred from a hotter object to a colder object, like heating a pan of water on a stove.

Energy transferred through waves, like sound waves or electromagnetic waves.

The process of transferring energy from one form to another.

The ratio of useful energy output to total energy input, expressed as a decimal or percentage.

A diagram that shows the flow of energy through a system, using arrows to represent the amount of energy transferred in each form.

The energy that is transferred into a useful form. For example, in a light bulb, light energy is the useful energy output.

Total energy input represents the total amount of energy provided to a system. For example, the total electrical energy provided to a light bulb.

A device that converts electrical energy into light energy, but also produces heat as a byproduct, making them inefficient, meaning most of the energy is wasted as heat.
