In order for gravitational potential energy to be stored, there must be . 1. An object position at some height in a gravitational field

2. an object positioned at a height of 0 in a gravitational field

3. an object positioned at some height outside a gravitational field

4. an object in motion

1

an object positioned at some height in a gravitational field

Explanation:

Gravitational potential energy of an object is the energy stored due to position of the object or position at certain height relative to zero position.

Gravitational potential energy can also be expressed as object position at some height above or below zero position in a gravitational field

I think 1 and 2 make sense. But 1 make more sense than 2
