1
Q
How many degrees is 2π radians?
A
360°
2
Q
What is the equation for angular displacement (θ)?
A
θ = s / r
Where s = arc length
and r is the radius of the circle.
3
Q
What is the definition of angular velocity?
A
The angle an object moves though per unit time.
4
Q
What are the equations for angular velocity?
A
⍵ = v / r ⍵ = 2π / T

A
Towards the centre of the object’s orbit.
6
Q
