A 10-kg mass and a 5-kg mass both sit on the same level shelf. Compare the gravitational potential energies of the two masses.

10 Kg mass has double the potential energy of 5 kg mass

Explanation:

Potential energy, is given by mgh where m is the mass of the object, g is acceleration due to gravity and h is the height

For 10 Kg mass

PE= 10gh

For 5 Kg mass

PE= 5gh

10gh=5gh*2

This means as mass increases, potential energy increases. 10 Kg mass has double the potential energy of 5 kg mass
