Aball rolls from point a to point b. the total energy of the ball at point a isn’t the same as the sum of its potential energy and kinetic energy at point b. which statement best explains this situation?
1the rolling ball doesn’t follow the law of conservation of energy.
2some of the ball’s energy is transformed to thermal energy.
3the rolling ball loses some of its energy because of gravity.
4the ball absorbs some of its own potential energy.
