Question 18 (Mandatory) (2 points) Consider a ball accelerating down a hill. Which statement is true as the ball rolls down the
hill? Question 18 options: The thermal energy decreases The potential energy decreases and the kinetic energy increases The kinetic energy decreases The potential energy and the kinetic energy both increase The potential energy and the kinetic energy both decrease
Answer: The potential energy decreases and the kinetic energy increases
Step-by-step explanation:
When a body is at rest , the Potential energy is maximum because the body is not moving and the acceleration is therefore zero but as soon as the body starts moving , it will convert the potential energy to kinetic energy , therefore the kinetic energy will therefore increase.
