Give three examples of rotational motion.

Define: Radian

Define: Angular displacement

Give the formula for angular displacement.

Give two examples in which this measure
would be relevant.

A girl sitting on a merry-go-round moves
counterclockwise through an arc length of 2.50 m. If the girl’s angular
displacement is 1.67 rad, how far is she from the center of the merry-go-round?

Define: Angular speed

Give the formula for angular speed.

Give two examples in which this measure
would be relevant.

A car tire rotates with an average angular
speed of 29 rad/s. In what time interval will the tire rotate 3.5
times?

Define: Angular acceleration

Give the formula for angular acceleration.

Give two examples in which this measure
would be relevant.

What angular acceleration is necessary
to increase the angular speed of a fan blade from 8.5 rad/s to 15.4 rad/s
in 5.2 seconds?
