Quiz I

Note that answering some of the questions below may require that the reader follow the links branching off the main body of the course.

1. Imagine a rotating disc relative to which a body is moving, or think of the experiments with the turning paper sheet. What is the direction of deflection on a disc turning counter-clockwise?

A to the left of the direction of velocity

B to the right

2. What is the cause of the phenomenon of deflection?

A changes in the rotation of the disc

B the observation/drawing technique

C the rotation of the disc

3. How will the deflecting force change if the angular velocity of the rotating disc is doubled?

A it will double

B it will be half as large

C it will not change

4. How will the deflecting force change if the velocity of the moving body is doubled?

A it will double

B it will be half as large

C it will not change

5. If the displacement $L$ of the moving body on the rotating disc doubles, how will the deflection $D$ and the relative deflection, that is quantity $D/L$, change?

A both will double

B $D$ will be twice as much, $D/L$ will be four times as much

C $D$ will be four times as much, $D/L$ will double

D both will be four times as much

6. What determines the path of the object on a carousel?

A only the Coriolis force

B only the centrifugal force

C both
