Question

An object of mass 65 kg is raised to a height of 20 m. Calculate the gravitational potential energy possessed by object. (The force of gravity on mass 1 kg is 10 N).

Answer 1

Answer:

Data:

mass (m) = 65 kg

height (h) = 20 m

G.P.E = ?

Formula:

G.P.E = mgh

G.P.E = 65 × 9.8 × 20

G.P.E = 12740 J
