What is an Eccentric force?

• A force applied within an objects centre of mass

• A force applied outside an objects centre of mass

What is Torque?

• Applying the same force further away from an object

• A increase in force applied to an object

• A turning force which causes rotation

• Applying the same force closer to an object

What is Angular Displacement?

• Largest change in angle between start and finish position.

• Smallest change in angle between start and finish position.

• The rotational speed an object is travelling at.

• The rate of change of angular velocity.

What is Angular Velocity?

• The rotational speed an object is travelling about an axis.

• The rate of change of an objects speed about an axis.

• The resistance of the body to rotate.

• Smallest change in angle between start and finish position.

What two factors affect an objects moment of inertia?

• Weight

• Mass

• Distance of mass from Axis

• Gravity

What is the equation to work out Angular Momentum?

• Moment of Inertia X Angular Velocity

• Moment of Inertia X Angular Momentum

• Moment of Inertia X Angular Displacement

• Moment of Inertia X Angular Motion

What is the equation for Angular Velocity?

• Angular Velocity / Time Taken

• Angular Displacement X Time Taken

• Angular Displacement / Time Taken

How can an athlete change their speed of rotation?

• Changing the direction they spin.

• Altering their body shape

• Applying more torque in a spin.

• Applying more force in a spin.
