Reading Quiz: Circular Motion

Answers must be submitted by 8:00am Monday, Feb 18th.

Read CP Chapter 9 Sections 1-4 and P3 Chapter 7 Section 3 up to "Changing Circular Motion"

Enter your last name, first initial:  

Click here to indicate that you have read the assigned material and are answering the reading questions on your own.

1. State the definition of "period"  (5 words or fewer)

       

2.  State the definition of "tangential" (3 words or fewer)

      

3.  State the definition of "centripetal" (3 words or fewer)

       

The diagram below shows a birds-eye view "snapshot" of a rotating turntable on which two pennies are sitting. The turntable and pennies are rotating clockwise with a period of 1.33 second. The pennies move at a constant speed.

                                         

 

 

 

 

 

 

 

4.  When the pennies in the diagram are at the locations indicated, what is the direction (relative to the diagram) of each penny's velocity?  What direction is its acceleration?

    Velocity

        Up     Down

        Left    Right

    Acceleration  

        Up     Down

        Left    Right

5. The bottom penny's motion has a radius of 10cm. Calculate the following quantities for that penny:

        Tangential speed:  m/s

        Centripetal speed: m/s

        Tangential acceleration: m/s2

        Centripetal acceleration: m/s2

6. The top penny's motion has a radius of 20cm. Calculate the following quantities for that penny:

        Tangential speed:  m/s

        Centripetal speed: m/s

        Tangential acceleration: m/s2

        Centripetal acceleration: m/s2

7. Use the period of the motion to calculate the angular speed in units of revolutions per second.  (This is also called the frequency of the motion).

        Angular speed (frequency) :    revolutions/sec

How many revolutions per minute does this equal ?

       Angular speed (frequency) :    revolutions/minute

8. What force provides centripetal acceleration to a car rounding a curve? 

       

9. Describe what would happen if the force providing centripetal acceleration to a car rounding a curve were to suddenly disappear.  Which of Newton's laws supports your answer?  Explain briefly.
