A person is skateboarding is part of a closed system that is 1450 j of mechanical energy at the kinetic energy of the prison increases from 200 J to 825 j what happens to the gravitational potential energy of the system

As the kinetic energy increases, the potential energy decreases.

Explanation:

Total mechanical energy = 1450 J

initial kinetic energy = 200 J

Final kinetic energy = 825 J

The mechanical energy is the sum of kinetic energy and the potential energy.

According to the law of conservation of energy, energy can neither be created and nor be destroyed, it can transform from one form to another.

So, here,

initial potential energy = 1450 - 200 = 1250 J

Final potential energy = 1450 - 825 = 625 J

Thus, we can conclude that if the kinetic energy increases the potential energy decreases.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
