Angular

What are the units for angular velocity

• m/s2

• rad/s

• kgm/s

• kg/m2

A record spins at 33 rpm (revolutions per minute), which is an angular velocity of about 3.46 radians per second. What is the approximate linear velocity of a fly that sits on the record, 12 cm from the center?

• 3.4 cm/s

• 21.5 cm/s

• 41.5 cm/s

• 131.9 cm/s

Klyde's angular velocity is

• the same as Bonnie's

• twice Bonnie's

• half of Bonnie's

• 1/4 Bonnie's

In the equation v=ωr, ω represents...

• Angular velocity measured in radians

• Angular velocity measured in degrees

• Angular velocity measured in revolutions

• The central angle measured in radians

What are the units for angular displacement.

• m/s

• kgm2/s

• radians

• rad/s

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

The time required for one complete revolution is:

• torque

• frequency

• period

• rotational kinetic energy
