Energy Physics

The energy calculator uses fundamental physics formulas:

• Kinetic Energy: KE = ½mv² (energy of motion)
• Potential Energy: PE = mgh (energy of position)
• Standard gravity: g = 9.81 m/s² (Earth's gravitational acceleration)
• Energy unit: Joule (J) = kg⋅m²/s²

Understanding Energy Calculations

Energy is the ability to do work. Our energy calculator helps you find how much energy an object has. There are two main types of energy this calculator can find.

Kinetic energy is the energy of moving things. When a car drives or a ball flies, it has kinetic energy. The faster something moves, the more kinetic energy it has.

Potential energy is stored energy. When you lift something up high, it gains potential energy.
