Angular Impulse-Momentum Principle

 

Angular impulse-momentum principle

 

The impulse of the resultant moment acting on a particle is equal to the change in the particle's angular momentum.

 

∫∑M_O dt = (r₂ x mv₂) - (r₁ x mv₁)

 

Time rate of change of angular momentum

 

Taking the time derivative of the angular impulse-momentum equation we get the following equation.

 

dH_O /dt = ∑M_O
