Gravitational potential energy (GPE) relies on weight and height.
The formula for gravitational potential energy is given by:
\[ \text{GPE} = mgh \]
where:
- \( m \) is the mass,
- \( g \) is the acceleration due to gravity (which relates to weight), and
- \( h \) is the height above a reference point.
Thus, the correct answer is weight and height.
