Circular Motion Flashcards
1
Q
One radian
A
The angle sub tended at the centre of a circle when the arc length of a sector is equal to the radius of the circle
2
Q
Period
A
The time taken in seconds for one complete circular path
3
Q
Angular velocity
A
The rate of angular rotation rad s^-1
4
Q
Centripetal acceleration
A
The acceleration of an object moving with uniform circular motion
a = v^2/r, a =ω^2r
5
Q
Centripetal force
A
The resultant force of an object, acting towards the centre of the circle, causing it to move in a circular path.
F = (mv^2)/r, F = mω^2r
