Frequently Asked Questions
What is the formula for kinetic energy?
The formula for kinetic energy is KE = ½mv², where KE is kinetic energy, m is mass, and v is velocity. Kinetic energy is the energy an object possesses due to its motion.
What units does this calculator support?
Our kinetic energy calculator supports kilograms, grams, pounds, and ounces for mass; meters per second, kilometers per hour, miles per hour, and feet per second for velocity; and Joules, kilojoules, calories, and BTU for energy.
Can I calculate mass or velocity from kinetic energy?
Yes, you can solve for any variable. If you know kinetic energy and velocity, you can calculate mass. If you know kinetic energy and mass, you can calculate velocity.
What is the difference between kinetic and potential energy?
Kinetic energy is the energy of motion (½mv²), while potential energy is stored energy due to position or configuration. The total mechanical energy is the sum of kinetic and potential energy.
