1
Q
Angular motion
A
- movement that takes place around an axis or fixed point
2
Q
Torque
A
- The force created that turns the body around an axis
3
Q
newtons 1st law (angular motion)
A
A rotating body will continue with constant torque until a large enough external force is acted up upon it
4
Q
newtons 2nd law (angular motion)
A
- The rate of change of angular motion is proportional to the force changing it.
The change in speed for of angular motion is often down to position
5
Q
newtons 3rd law (angular motion)
A
When torque is applied, there will be always be an equal and opposite force
6
Q
Angular displacement
A
- is the smallest change in angle between the start and finish points of a rotation.
- It is measured in degrees and radians
7
Q
Angular velocity
A
- is the rotational speed of an object.
- It refers to the rate of change of angular displacement
8
Q
Angular Acceleration
A
- is the rate of change of angular velocity
9
Q
angular momentum (equation)
A
Angular momentum = moment of inertia x angular velocity
10
Q
Conservation of angular motion - decreasing
A
- To slow down angular motion, a performer must increase their moment of inertia
- This is achieved by opening out their limbs and their body
11
Q
Conservation of angular motion - increasing
A
- To increase angular motion, a performer must decrease their moment of inertia
- This is achieved by tucking their body/bringing their arms together
