If you're talking about Kinetic Energy and Gravitational Potential Energy (or Potential Energy), there are 2 formulas. For Kinetic Energy, the formula is ½ × m × v². For Gravitational Potential Energy, it's m × g × h.
Explanation:
Kinetic Energy:
KE = ½ × m × v²
wherein;
m = mass of the object
v² = velocity squared (note: In solving, acceleration and velocity are often confused because the unit for acceleration is m/s² while the unit for velocity is m/s.)
Gravitational Potential Energy
PE = m × g × h
wherein;
m = mass of the object
g = acceleration due to gravity (this is always 9.8 m/s²)
