Newton's Laws of Angular Motion

Question 1

What is Newton’s first law of angular motion?

Answer 1

The angular momentum of a rotating body is constant unless acted upon by an external torque (rotation)

Question 2

What is Newton’s second law of angular motion

Answer 2

A torque applied to an object will cause a change in angular motion in the direction of the applied torque that is directly proportional to the size on the torque applied and inversely proportional to the moment of inertia

Torque = Mass x Angular Acceleration

Question 3

What is Newton’s third law of angular motion?

Answer 3

For every torque there is an equal and opposite torque.
