Question

Write equations and laws of rotational motion​

Answer 1

Answer:

Newton's First Law for Rotation: an object at rest tends to remain at rest, and an object that is spinning tends to spin with a constant angular velocity, unless it is acted on by a nonzero net torque or there is a change in the way the object's mass is distributed. ... Always remember to add torques as vectors.

Answer 2

Answer:

If more than one torque acts on a rigid body about a fixed axis, then the sum of the torques equals the moment of inertia times the angular acceleration: ∑iτi=Iα. This is called the equation for rotational dynamics. ...
