How can we increase the gravitational potential energy of the car?

Strap a boulder to the car so that it contains more mass.

Keep the length of the hill at 50 m but only 5 m tall.

Take the interior out of the car so that the car has less mass.

Keep the hill at 10 m tall but increase the length of the hill so that the car has farther to roll.

Which of the following expressions correctly represents the gravitational potential energy of an object?

Pe=m⋅g⋅hP_e=m\cdot g\cdot h

Pe=12⋅m⋅v2P_e=\frac{1}{2}\cdot m\cdot v^2

Pe=m⋅g⋅vP_e=m\cdot g\cdot v

Pe=m⋅g⋅h2P_e=m\cdot g\cdot h^2
