How to use

1. Enter object mass m.
2. Enter velocity v for kinetic energy computation.
3. Enter height h for gravitational potential energy.
4. View resulting kinetic, potential, and total mechanical energy in Joules (J).

Calculation Example

For a 2 kg mass at height 10 m with velocity 5 m/s (g = 9.81 m/s²):

Kinetic energy Ek = (m*v²)/2 = (2 * 25) / 2 = 25 J.

Potential energy Ep = m*g*h = 2 * 9.81 * 10 = 196.2 J.

Total mechanical energy E = Ek + Ep = 25 + 196.2 = 221.2 J.

Calculation Methodology

Kinetic energy follows Ek = 1/2 * m * v². Potential energy follows Ep = m * g * h. In conservative systems without friction losses, mechanical energy is conserved: Ek + Ep = const.
