Rotational Dynamics

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

If the body is moving in a circle of radius r with a constant speed v, its angular velocity is

• v² / r

• vr

• v / r

• r / v

Klyde's angular velocity is

• the same as Bonnie's

• twice Bonnie's

• half of Bonnie's

• 1/4 Bonnie's

The time required for one complete revolution is:

• torque

• frequency

• period

• rotational kinetic energy

In the equation

$v=\omega r,\ \ \omega\ represents...$

• Angular velocity measured in radians

• Angular velocity measured in degrees

• Angular velocity measured in revolutions

• The central angle measured in radians

• angular velocity
  

• angular acceleration

• rotational inertia 

What is angular velocity

• the rate of angular displacement of an object

• the resistance of an object to change its current state

• the amount of angular motion of an object

The moment of inertia:

• is synonymous with mass
• does not depend on where the mass is located
• resistance to a change in rotational inertia
• more resistance to change = less inertia
