Answer: The factors that affect an objects gravitational potential energy are mass and height of the object, acceleration due to gravity and gravitational field strength.
Step-by-step explanation:
The height or vertical distance of the object above a reference point or the ground plays an important role in the gravitational potential energy of the object. The higher the height of the object, the greater the potential energy it has. Similarly, the mass of the object also has an influence on the potential energy. Objects with greater mass have higher potential energy than objects with lesser mass when both are positioned at the same height.
