Question

An object that is 3 times higher than another object of the same mass will
have times the gravitational potential energy.
OA) 1.5
OB) 3
OC) 6
OD 9

Answer 1

Answer:

OB) is the correct answer. 3 times

Explanation:

Gravitational potential energy of an object is the energy of that object possesses due to its position in the gravitational field. As we know that an object cannot be lift up until the lifting force is greater than weight of the object. So it follow that  gravitational potential energy is the weight times the height to which it is lifted.

                  gravitational potential energy = weight × height

                                                   PE  =  mgh

It can be seen from the formula that PE has linear relation with height. So if height is X times higher than other object, gravitational potential energy  also X time higher.
