Online Kinetic Energy Calculator
Calculate kinetic energy KE = ½mv² from mass (kg) and velocity (m/s). Result in joules.
Frequently Asked Questions
- What formula is used?
- KE = 0.5 × mass × velocity². Mass in kg, velocity in m/s, result in joules (J).
- Can I use other units?
- Use consistent units; the result will be in the corresponding energy unit (e.g. kg and m/s give J).
