Angular Newton's Laws Flashcards
1
Q
Newtons first law
A
A rotating body will maintain a state of constant rotational motion unless acted on by an external torque.
2
Q
Newtons second law
A
A net torque produces angular acceleration of a body that is directly proportional to the magnitude of the torque, in the same direction as the torque, and inversely proportional to the body’s moment of inertia.
3
Q
Newtons third law
A
For every torque exerted by one body on another, there is an equal and opposite torque exerted by the second body on the first.
4
Q
moment of inertia
A
resistance to angular acceleration
5
Q
angular momentum
A
moment of inertia x angular velocity
angular momentum is conserved without eternal torques (newtons 1st law)
