Physics
Potential Energy
Calculate gravitational potential energy near Earth.
PE = mgh
Formula Explanation
The formula applies for changes in height near a nearly uniform gravitational field.
Variables Explained
m = Mass; g = Gravitational acceleration; h = Height change.
Solved Example
Find PE for a 2 kg object raised 5 m, using g = 9.8 m/s².
PE = 2 × 9.8 × 5 = 98 J.
