1
Q
What are angles measured in for circular motion ?
A
Radians
2
Q
How to convert frequency and time period
A
frequency = 1 / time period
3
Q
What is the angular velocity equation ?
A
ω = 2π / T = 2πf
4
Q
What is centripetal force ?
A
It is the net force which acts towards the centre of the circle and perpendicular to the direction of motion
5
Q
What is the equation of velocity of an object moving in a circle ?
A
v = 2πr / t = ωr
6
Q
What is the equation for centripetal acceleration
A
a = v^2/r = ω^2r
