Physics of the Ferris Wheel Quiz

What is the primary goal of the video tutorial on the physics of the ferris wheel?

• To discuss the design of ferris wheels

• To calculate the speed of the ferris wheel

• To determine the normal force at three locations

• To explain the history of ferris wheels

In uniform circular motion, what remains constant?

• Acceleration

• Speed

• Direction

• Velocity

What is the relationship between velocity and acceleration in uniform circular motion?

• Velocity is constant, acceleration is zero

• Velocity is constant, acceleration changes

• Velocity changes, acceleration is constant

• Both velocity and acceleration are constant

When a person is stationary on the ferris wheel, what is the normal force equal to?

• Half the gravitational force

• The gravitational force

• Twice the gravitational force

• Zero

What happens to the normal force at the top of the ferris wheel?

• It becomes zero

• It equals the gravitational force

• It is greater than the gravitational force

• It is less than the gravitational force

Why is the normal force less at the top of the ferris wheel?

• Because of decreased mass

• Because of centripetal acceleration

• Due to increased speed

• Due to gravitational pull

At the bottom of the ferris wheel, how does the normal force compare to the gravitational force?

• It is greater than the gravitational force

• It is equal to the gravitational force

• It is less than the gravitational force

• It is zero

What causes the normal force to be greater at the bottom of the ferris wheel?

• Decreased mass

• Centripetal acceleration

• Decreased speed

• Increased gravitational force

How does the apparent weight at the bottom of the ferris wheel compare to the true weight?

• Apparent weight is less than true weight

• Apparent weight is equal to true weight

• Apparent weight is greater than true weight

• Apparent weight is zero

What is the effect of centripetal acceleration on the normal force at different points on the ferris wheel?

• It doubles the normal force

• It eliminates the normal force

• It causes the normal force to vary

• It makes the normal force constant
