Potential energy of a 20 kg suitcase lifted 1.5 m

Answer: potential energy = 294.2 J (in kilowatt-hours 8.172e-5 kWh, in food calories 0.07 kcal).

What we know

  • Mass: 20 kg
  • Height: 1.5 m

Step by step

Given
m = 20 kg, h = 1.5 m
Formula
PE = m × g × h
Substitute
PE = 20 × 9.80665 × 1.5
Result
PE = 294.2 J

All results

The physics

Gravitational potential energy is stored height: mass × gravity × elevation. Lift something up and you bank energy; let it fall and the bank pays out as motion, heat or electricity.
