Kinetic Energy Calculator
Work out the kinetic energy of a moving object, or rearrange E = ½mv² to find its mass or speed. You can also find how much kinetic energy changes when an object speeds up or slows down.
What you can do
- Find energy, mass or speed, with the rearrangement shown
- Change in kinetic energy between two speeds
- Momentum and the effect of doubling the speed or the mass
- Graph of energy against speed
- Units including km/h, mph, grams and tonnes
