Question

How much work is done by the force of gravity went 45 n object falls to the ground from a height of 4.6m?

Answer 1

The work W exerted over an object by a force F along a distance d is:

`W=Fd`

Substitute F=45N and d=4.6m to find the work done by the force of gravity on the falling object:

`W=(45N)(4.6m)=207J`

Therefore, the work done by the force of gravity when a 45N object falls a distance of 4.6m, is:

`207J`
