Formula Used in the Energy Calculator
Kinetic Energy Formula
KE = 0.5 × Mass × Velocity²
KE = ½mv²
Potential Energy Formula
PE = Mass × Gravity × Height
PE = mgh
Mechanical Energy Formula
ME = Kinetic Energy + Potential Energy
ME = KE + PE
Formula Components
- Mass (m): Can be in kilograms, grams, or pounds
- Velocity (v): Can be in m/s, km/h, or mph
- Height (h): Can be in meters or feet
- Gravity (g): 9.8 m/s² (standard value)
- Energy: Usually expressed in Joules (J), calories, or kWh
Example Calculations
Kinetic Energy: A 10 kg object moving at 5 m/s:
KE = 0.5 × 10 × 5² = 125 J
Potential Energy: A 10 kg object at 10 m height:
PE = 10 × 9.8 × 10 = 980 J
These formulas ensure accurate and consistent energy calculations.
