Presentation transcript:

Impulse and Momentum Impulse and momentum stem from Newton’s Second Law: Impulse (FΔt): The product of the force and the time it acts on an object. (N·s) Momentum (ρ = m Δv ): The product of mass of an object and its velocity. (kg·m/s) Impulse Momentum Theorem: Equation seen here.

Angular Momentum Angular Momentum (L): The product of a rotating object’s moment of inertia and its angular velocity. (kg·m 2 /s)

Conservation of Momentum Closed System: A system where no mass is gained or lost Isolated System: No external forces interfering. Conservation of Momentum: Momentum in a closed, isolated system will never change.
