Calculation of Energy
Potential Energy of a system can be calculated by multiplying the mass of an object, the gravitational pull, and the height at which the object is dropped.
The mass x gravity = Weight of the object PE = mass x gravity x height PE is given in Joules (J) Mass is given in kilograms (kg) Gravity is given in meters/second2 (m/s2) Height is given in meters (m) |
