Frequently Asked Questions

What's the difference between kinetic and potential energy?

Kinetic energy is the energy of motion (KE = ½mv²), while potential energy is stored energy due to position or configuration (like gravitational potential energy = mgh).

Can I use negative values?

No, mass and velocity must be positive values since they represent physical quantities that cannot be negative.

What if velocity is zero?

If velocity is zero, the kinetic energy will be zero since KE = ½mv² = ½m(0)² = 0.

How do I convert between different energy units?

The calculator automatically handles unit conversions. Simply select your desired output unit and the result will be converted accordingly.
