A ball 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?

The rolling ball doesn’t follow the law of conservation of energy.

Some of the ball’s energy is transformed to thermal energy.

The rolling ball loses some of its energy because of gravity.

The ball absorbs some of its own potential energy.

The rolling ball loses some of its energy because of gravity. Gravity and friction are two factors that slows the acceleration of the ball causing the ball to slow down at point B. If the situation is a free fall, then gravity is a factor, but if it is in a horizontal displacement,then there is friction that counterflows against the applied force.

Conservation of mechanical energy

The principle of conservation of energy states that sum of potential energy and kinetic energy is constant.

M.A = P.E + K.E

where;

  • P.E is the potential energy
  • K.E is the kinetic energy

The mechanical energy is always conserved, although it may be converted from one form to another.

The rolling ball follows the law of conservation of energy, the lost energy may be transformed to thermal energy.
