Question

A force of 18N is used to lift an object over a height of 2m. Calculate potential energy gained by object

Answer 1

Answer:

potential energy = mass×height×gravity

but here we have only force...

formula of force=mass×gravity

therefore,,

F=m×g

18N=m×10...(gravity=10m/s²)

m=18/10

m=1.8kg

so the potential energy will be...

1.8×2×10

36joule..
