Question

alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill. the motionless ball has potential energy. once the ball starts to roll down the hill, new kinetic energy is made. as the ball rolls across the grass, it slows down. the kinetic energy of the ball is converted to other forms of energy. which best describes alanas error? the motionless ball does not have energy because it is still. kinetic energy is not made; it is a result of energy transformation. the ball cannot slow down unless someone touches it. the energy is not converted; it disappears.

Explanation:

According to the law of conservation of energy, energy cannot be created or destroyed, only transformed. When the ball rolls down the hill, its potential energy is transformed into kinetic energy, not new kinetic energy being made.

Answer:

Kinetic energy is not made; it is a result of energy transformation.
