Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.

Calculation of work done against gravity:
- Gravitational force acts in a downward direction.
- As a result, the work done by gravity on a freely falling item is given by:
Work against gravity = mass x acceleration due to gravity x height
W = mgh
- The formula for force is mg, where m is mass and g is the acceleration due to gravity, which is 9.8 m/sec^2.
- Because only the vertical distance an item moves is important for computing work against gravity, we use h for height.
