5.2.1: Kinematics of Circular Motion Flashcards
1
Q
Radian
A
Unit of measurement of an angle: 1 Radian = 57.3°. 1 radian of angle is subtended when the arc length of a circle is equal to the radius.
2
Q
Time period
A
The time taken for one complete oscillation (SI units of seconds)
3
Q
Frequency
A
The number of complete oscillations per unit time (one second) (Hz OR s-1). Frequency = 1/Period
4
Q
Angular velocity
A
Rate of change of angular displacement
5
Q
Linear speed
A
Angular velocity multiplied by radius
6
