Final answer:

In a roller coaster scenario, mechanical energy undergoes transformations as the coaster moves through hills, converting between gravitational potential and kinetic energy.


Explanation:

Changes in mechanical energy in a roller coaster starting at the top of a hill involve transformations between gravitational potential energy and kinetic energy. As it goes down the first hill, potential energy decreases while kinetic energy increases. When it goes up the second hill, kinetic energy decreases as potential energy increases again. This cycle continues, with some energy lost to heat due to friction.
