A ball of mass 0.5 kg thrown upwards reaches a maximum height of 5m. Calculate the work done by the force of gravity during this vertical displacement considering the value of `g = 10 m//s^(2)`.

Text Solution

Verified by Experts

Force of gravity acting on the ball
`F = mg = 0.5 xx 10 = 5 N `
Displacement of the ball, S = 5m
The force and displacement are in opposite directions . Hence work done by the force of gravity on the ball is negative .
`W = - F S `
`= - 5 xx 5`
`- 25 J `
