1
Q
Define the radian
A
A circle contains 2pi radians (360 degrees)
2
Q
What are the conditions for an object taking a circular path?
A
When a force perpendicular to the velocity of an object is applied to that object
3
Q
What is centripetal force?
A
When an object has circular motion, centripetal force is the net force acting on the object towards the centre of the circle. This causes centripetal acceleration
4
Q
What is centripetal acceleration?
A
The rate of change of velocity perpendicular to the centripetal force
5
Q
What is the equation for centripetal force?
A
F = ma = (mv^2)/r
6
Q
What is the equation for centripetal acceleration?
A
a = (v^2)/r
7
Q
What is the equation for circular velocity?
A
v = (2pir)/T
