Angular motion

Question 1

What is angular motion ?

Answer 1

Movement around an axis

Question 2

What is a torque ?

Answer 2

The amount of turning force that is generated by a resistance

Question 3

What is the calculation for torque ?

Answer 3

Torque = resistance * distance from axis

Question 4

How can Newton’s first law be related to angular motion ?

Answer 4

First law = a rotating body will continue to turn around it’s axis of rotation constantly until a torque (external force is applied)

Question 5

How can Newtons second law be applied to angular motion ?

Answer 5

The rate of change of angular momentum of a body is proportional to the force causing it and one change that takes place in the direction in which the force acts

Question 6

How can Newtons third law be applied to angular motion ?

Answer 6

When a force is applied by one body to another, the second body exerts an equal and opposite force on the body
