Question

Does a ball rolling on an inclined plane have the same acceleration on
the way up as it does on the way down? Justify your answer.​

Answer 1

A ball rolling on an inclined plane will not have the same acceleration on  the way up as it does on the way down.

Explanation:

• A ball rolling down on an inclined plane will have a different acceleration than a ball rolling up the inclined plane

• The acceleration of the ball rolling down the inclined plane will be more than the acceleration of the ball rolling up the inclined plane

• The reason for this is that while the ball is rolling down, the component of acceleration due to gravity in the direction of the motion of the ball $g\sin\theta$ will act in the direction of the motion of the ball and hence it helps in the acceleration of the ball while when the ball is going upwards, the same component of acceleration acts in the opposite direction of the direction of motion of the ball and hence reduces the acceleration.

Hope this answer is helpful.

Answer 2

Answer:

No, the acceleration on the way up is greater than the way down!

Explanation:

In a frictionless environment, the acceleration of an object depends only on the force of gravity and its mass. Therefore, its acceleration will be the same rolling up a ramp than it is rolling down the ramp since there is no force to slow it down or speed it up. But unfortunately the world is not frictionless and not as simple. The acceleration of an object when rolling up a ramp is greater than the acceleration of an object rolling down the same ramp. This is due to the force of kinetic friction, which resists motion. It is further explained by Newton's second law of motion, which states that "force is equal to mass times acceleration."  

I really recommend this video from YouTube, he explains this problem well with free-body diagrams.
