Here's some bantha fodder for your notecard !. MOMENTUM IS CONSERVED!!!. For ALL Collisions/Separations: p before = p after. General Equations: Momentum = Inertia in Motion p = mv Impulse = Change In Momentum I = Δ p = ( p f - p i ) Ft = m Δ v = m( v f - v i ).

MOMENTUM IS CONSERVED!!! For ALL Collisions/Separations:pbefore= pafter General Equations: Momentum = Inertia in Motion p = mv Impulse = Change In Momentum I = Δp = (pf - pi) Ft = mΔv = m(vf - vi) Explosions/Separations: (2 objects stuck together separate) p1,2 = p1 + p2 (m1 + m2)v = m1v1 + m2v2 0 = m1v1 + m2v2 -m1v1 = m2v2 If no motion before: The two objects have EQUAL and OPPOSITE Momentums. The negative sign just shows direction!!! Inelastic Collisions: (2 objects collide and STICK together) p1 + p2 = p1,2 m1v1 + m2v2 = (m1 + m2)v Elastic Collisions: (2 objects collide and BOUNCE apart) p1 + p2 = p1' + p2' m1v1 + m2v2 = m1v1' + m2v2'
