Angular velocity OCR

Which one of these is not a key descriptor for angular motion.

• Angular momentum

• Angular velocity

• Moment of Inertia

• Displacement

What are the units for angular displacement.

• m/s

• kgm2/s

• radians

• rad/s

What are the units for angular velocity

• m/s2

• rad/s

• kgm/s

• kg/m2

The sum for Angular velocity is angular ...................... (rad) divided by time taken (s).

The equation for moment of inertia is ...

• $MI=\sum_{ }^{ }\ m\ \times\ r^2$

• $MI\ =r\ \times\ m$

• $MI\ =\ \frac{m}{r^2}$

• $MI\ =\sqrt{A\ +S}$

Moment of Inertia combines the mass of a body (kg) with .....

• speed of the body

• velocity of the body

• distance of the body from the Center of Mass²

• radians

The units for Moment of Inertia are..

• Kg/s²

• m/s²

• kg/m

• kgm²

Moment inertia is known as the amount of ..................... to angular acceleration.

As the moment of inertia increases (arms move away from the COM) angular velocity ..........................

Angular momentum =

• Moment of inertia - angular velocity

• Moment of inertia x angular velocity

• Angular velocity + moment of inertia

• Angular velocity / Moment of Inertia
