Angular Motion and Newton's Analogues

Question 1

What is angular motion

Answer 1

Angular motion involves rotational movement around a fixed point or axis

Question 2

What is Newton’s first law of angular motion

Answer 2

A rotating body will continue to turn about its axis of rotation with constant angular momentum unless an external rotational force (torque) acts on it

Question 3

What is Newton’s second law of angular motion

Answer 3

The angular acceleration of a body is proportional to the force (torque) causing it to change and in the direction in which the force (torque) acts

Question 4

What is Newton’s third law of angular motion

Answer 4

When a force (torque) is applied by one body to another, the second body will exert an equal and opposite force (torque) on the other body.

Question 5

Define torque and what is its equation
(INCLUDE THE UNITS)

Answer 5

Torque-rotational consequence of a force

Moment of torque(Nm)=force(N)xperpendicular distance from the fulcrum(m)
