Hello mayazhanmath!

 

How much work is needed to lift an object that weighs 150 N to a height of 5 m?

 

 

\(The \ work \ done \ is \ 150N \times 5m.\)

 

\(W=F\times s = 150N\times5m = 750\ Nm \ or \ 750\ Ws.\)

 

\(The \ gravitational \ potential \ energy \)

\(grows \ around \ this \ size.\)
