Chapter 6, Problem 94A

To determine

To Explain: The way physics of circular motion creates the sensations for the riders.

Explanation of Solution

Introduction:

When a body is travelling or moving in a circular path, it experiences centripetal acceleration. It tends to movetowards the center of the circular path.

Two rides are: Carousel and Pendulum ride.

The reason for sensations:

In case of carousel, the riders are in a circular motion moving with constant speed, but centripetal acceleration is being experienced by them because of the change in their direction. This explains the effect of circular motion that creates the thrills out of the riders.

In case of pendulum, it swings back and forth, which can be explained as an arc made by the swing. So, when the pendulum is at the top arc, it moves with the centripetal acceleration which is opposite to the acceleration due to gravity. Hence, involvement of circular motion is there.

Conclusion:

Thus, the two rides are: Carousel and Pendulum ride.
