Gravitational potential energy
PE = mgh
Where: PE = potential energy (J), g = acceleration due to gravity (m/s²), h = height (m) / Planck constant, m = mass (kg)
Solved example
Given: g = 7, h = 5, m = 10
Find: PE_ (potential energy (J))
- Formula: PE = g·h·m
- Substitute the values: PE = 10·5·7
- Result: PE = 350 J
Answer: PE_ = 350 J
