Answer 8

Radian

Question 9

Distance from the axis of rotation to a point of interest on a rotating body

Answer 9

Radius of rotation

Question 10

Procedure for identifying the direction of an angular motion vector

Answer 10

Right hand rule

Question 11

The greater the radius between a point on the rotating body and axis of rotation…

Answer 11

The greater the linear distance traveled during an ANGULAR motion

Question 12

Linear distance =

Answer 12

(Radius of rotation) * (Angular distance)

Question 13
