Gravitational potential energy is dependent on the object's mass, the strength of the gravitational field, and the height (or vertical position) of the object relative to a reference point. The formula for gravitational potential energy (U) is typically given by:
\[ U = mgh \]
where:
- \( U \) is the gravitational potential energy,
- \( m \) is the mass of the object,
- \( g \) is the acceleration due to gravity (the strength of the gravitational field),
- \( h \) is the height of the object above a chosen reference level.
So to summarize, the three factors are mass, gravitational field strength, and height.
