Angular & Linear motion relationship

Question 1

When is angular motion used to produce linear motion?

Answer 1

eg golf drive, hammer throw

higher angular velocity = ^ linear (tangential) velocity

Question 2

how does an increased radial length effect linear velocity?

Answer 2

greater length of radius eg out stretched arm for tennis serve increases linear velocity

Question 3

linear (tangential) velocity equation

Answer 3

linear (tangential) velocity (m/s-1) = Angular velocity (rad/s) x Length of radius (m)

Question 4

How can angular velocity be increased eg within hammer throw

Answer 4

Training the kinematic chain (peak angle velocity & timing of impact/release)
