Question

What is the potential energy of a 2,000-kg car parked at the top of a 30-m hill?

Answer 1

The potential energy of an object is the energy stored in an object related to its position.
Potential energy can be calculated as follows ;
P.E = m.g.h
Where M - mass of object
G - gravitational acceleration-9.8 m/s2
H - height from the ground
Substituting the equations
P.E = 2000 kg x 9.8 m/s2 x 30 m
P.E = 588 kJ
