Question

gravitational potential energy is always measured group of answer choices relative to the ground. relative to the center of the earth. relative to the center of the sun. relative to an arbitrary reference level.

Answer 1

The gravitational potential energy is always measured relative to the ground.

The gravitational potential energy of a system is related as.

PE = MgH

Where,

M is the mass of body,

g is the acceleration due to gravity,

H is the height of the body with respect to the ground.

As we know, for a particular surface on earth, the mass and g is always constant.

Only the height of the body is changing with respect to the ground, Hence we can conclude here, that gravitational potential energy of a body is measured with respect to the ground.
