The formula for potential energy depends on the type of energy that is stored. For gravitational potential energy, the formula is:

PE = mgh

Where:

• m is the mass of the object in kilograms (kg)
• g is the gravitational field strength (9.81 m/s^2 on Earth)
• h is the height of the object in meters (m)

This formula can be used to calculate the potential energy of an object based on its mass and height above a reference level. Other types of potential energy, such as elastic potential energy or chemical potential energy, have different formulas.
