Our kinetic energy calculator can help you calculate kinetic energy of an object as well as solve for the other factors of the formula such as mass and velocity. Kinetic energy is energy in motion. When an object gains velocity it gains the potential energy and is transformed into kinetic energy. The mass of that object is the other variable that determines the amount of energy that is being transferred.

For example, when a roller coaster reaches the top of a peak and starts to descend, the velocity of the cars increases which in turn increases the kinetic energy of the cars. When the cars slow down, the energy is converted back to potential energy. Ideally, once the roller coaster cars reach a certain speed, they would maintain that speed and kinetic energy without additional work. However, the cars will lose energy and speed due to the friction between the surfaces. Energy is not lost, but it is converted to another form.

You can use our kinetic energy calculator to solve the equation below. With this formula you can solve for any one of the variables as long as you know the other two. To solve for kinetic energy you would need to know mass and velocity. Simply enter the two values that you know and our calculator will solve the equation and give you the answer for the unknown variable.
