3

Is angular displacement a vector or scalar?q

vector (magnitude and direction)

4

What does angular position refer to?

The orientation of a line with another line or plane

5

What is absolute angular position

If the other line or plane is fixed

6

What is relative angular position

If the other line or plane is capable of moving

7

What are radians?

A measure of the length of an arc

8

What is angular velocity

change in angular displacement/ change in time

9

What is angular speed?

change in angular distance/ change in time

10

What is a torque?

The turning effect produced by a force
T= f x d
