Angular kinematics

Question 1

What is the formula for an arc?

Answer 1

Arc = angle*radius

Question 2

What is the formula for angular velocity?

Answer 2

w = changle in angle/change in time

Question 3

What is the formula for linear velocity?

Answer 3

v= radius*angular velocity

Question 4

What is the formula for torque?

Answer 4

moment arm*force

Question 5

What is a first class lever?

Answer 5

Force and resistance on opposing sides of axis of rotation

Question 6

What is a second class lever?

Answer 6

Force and resistance on same sides of axis of rotation, force further away

Question 7

What is a third class lever?

Answer 7

Force closer to axis than resistance

Question 8

What is static equilibrium?

Answer 8

Forces and torques = 0
