1
Q
What is constantly changing for an object in circular motion
A
constantly changing velocity
2
Q
If the velocity is constantly changing what must the object be doing
A
accelerating
3
Q
What force is the resultant force for an object in circular motion
A
centripetal force acting to centre
4
Q
What is angular speed
A
angle an object passes through per unit time
5
Q
How is angular speed calculated
A
v / r
2pi / T
2pi f
6
Q
How is centripetal acceleration calculated
A
a = V^2 / r
a = angular speed^2 * r
