Question

A metal sphere rests upon the exact center of a level, square table top. The table is sitting on the floor. Andrea knows the mass of the sphere; what other measurement does she need to calculate the potential energy of the sphere?

Answer 1

To calculate the potential energy of the metal sphere, Andrea would need to know the height at which the sphere is located.

Step-by-step explanation:

To calculate the potential energy of the metal sphere, Andrea would need to know the height at which the sphere is located above the floor. Potential energy is calculated using the equation PE = mgh, where m is the mass of the sphere, g is the acceleration due to gravity, and h is the height. By knowing the mass and the height, Andrea can calculate the potential energy of the sphere.
