Name linear motion quantities
name angular motion quantities
Is angular displacement a vector or scalar?q
vector (magnitude and direction)
What does angular position refer to?
The orientation of a line with another line or plane
What is absolute angular position
If the other line or plane is fixed
What is relative angular position
If the other line or plane is capable of moving
What are radians?
A measure of the length of an arc
What is angular velocity
change in angular displacement/ change in time
What is angular speed?
change in angular distance/ change in time
What is a torque?
The turning effect produced by a force
T= f x d
