# Conservation of Energy Calculator

Enter any three values of the initial and final kinetic energy of a system to calculator the missing value.

## Formula

The following equation describes the relationship of kinetic and potential energy due to the conservation of energy.

Ki + Ui = Kf + Uf

• Where Ki is the initial kinetic energy
• Ui is the initial potential energy
• Kf is the final kinetic energy
• Uf is the final potential energy

This formula describes the relations of potential and kinetic energy simply, but conservation of energy is also used in thermodynamics to calculate work and heat generated from systems.

## FAQ

What is conservation of energy?

The conservation of energy is a law of physics that states that in a closed system, energy must be conserved. For example, like the equation above, the kinetic energy and potential energy of a CLOSED system cannot change without and outside force or without the system acting on an outside object.

What is kinetic energy?

Kinetic energy describes the total amount of energy contained within a system due to translational movement.

What is potential energy?

Potential energy is the amount of energy contained in a system due to things like gravitational force and internal chemical reactions.
