Newton's Second Law for Rotation
Statement of Newton's Second Law for
Rotation: Στ = I
α
Very important: this equation is strongly origin
dependent!!
Basic facts about angular acceleration. The angular acceleration is:
- proportional to the net torque (a &prop F);
- inversely proportional to the moment of inertia (a &prop 1/m);
- proportional to the inverse of the mass;
- proportional to the inverse square of the size of the object
