Final answer:
False. Gravitational potential energy is not directly proportional to mass and height above a reference level.
Step-by-step explanation:
False
Gravitational potential energy is not directly proportional to mass and height above a reference level.
The formula for gravitational potential energy is given by P.E. = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. This formula shows that gravitational potential energy is determined by the mass and height, but it is not directly proportional to them.
For example, if you double both the mass and height of an object, the gravitational potential energy will increase by a factor of 4 (2^2) according to the formula.
