Work (W) = mgh
where:
* m is the mass of the body (in kilograms)
* g is the acceleration due to gravity (approximately 9.8 m/s²)
* h is the height the body is lifted (in meters)
Explanation:
* Force: The force required to lift the body is equal to its weight, which is *mg*.
* Displacement: The body is moved a distance of *h* vertically upwards.
* Work: Work is defined as the product of force and displacement in the direction of the force.
Therefore, the work done is equal to the force (mg) multiplied by the displacement (h), resulting in mgh.
