Question

When you place a ball at the top of a hill and it accelerates toward the bottom

Answer 1

Answer:

When a ball accelerates toward bottom it experiences both rolling friction and air resistance.

Explanation:

• When the ball rolls from the hill the gravitational force of attraction comes in action and accelerates the ball toward the bottom of the hill.
• This motion of ball is the rotational motion,  rolling friction acts on it due to rotational motion.
• As the velocity of the ball increases air resistance also starts to have significant effect on its motion.
• These two forces try to oppose the motion of the ball.
