Angular Displacement (θ)
The angle through which the object has moved in a circle.
1 of 6
Displacement (s)
The distance it has travelled from its starting position.
2 of 6
Radian
The angle subtended at the centre of a circle by an arc length equal to the radius of the circle.
3 of 6
Angular Velocity (w)
The rate of change of the angular position of an object as it moves along a curved path.
4 of 6
Centripetal Force (F)
The resultant force acting on an object moving in a circle; it is always directed towards the centre of the circle.
5 of 6
Orbital Speed (v)
The speed an object must have to orbit under gravity.
