1. Here's some bantha fodder for your notecard!

2. General Equations: Momentum = Inertia in Motion p = mv Impulse = Change In Momentum I = Δp = (p f - p i ) Ft = mΔv = m(v f - v i ) Explosions/Separations: ( 2 objects stuck together separate ) p 1,2 = p 1 + p 2 (m 1 + m 2 )v = m 1 v 1 + m 2 v 2 0 = m 1 v 1 + m 2 v 2 -m 1 v 1 = m 2 v 2 If no motion before: The negative sign just shows direction!!! The two objects have EQUAL and OPPOSITE Momentums. Inelastic Collisions: ( 2 objects collide and STICK together) p 1 + p 2 = p 1,2 m 1 v 1 + m 2 v 2 = (m 1 + m 2 )v Elastic Collisions: ( 2 objects collide and BOUNCE apart) p 1 + p 2 = p 1 ' + p 2 ' m 1 v 1 + m 2 v 2 = m 1 v 1 ' + m 2 v 2 ' For ALL Collisions/Separations:p before = p after MOMENTUM IS CONSERVED!!!

3. General Equations: Momentum=Inertia in Motion p=mv Impulse=Change In Momentum I= Δp=(p f - p i ) Ft= Δmv=m(v f - v i )

4. For ALL Collisions/Separations: p before =p after MOMENTUM IS CONSERVED!!!

5. Explosions/Separations: (2 objects stuck together separate) p 1,2 = p 1 + p 2 (m 1 + m 2 )v =m 1 v 1 + m 2 v 2 0 = m 1 v 1 + m 2 v 2 -m 1 v 1 =m 2 v 2 If no motion before: The negative sign just shows direction!!! The two objects have EQUAL and OPPOSITE Momentums.

6. Inelastic Collisions: (2 objects collide and STICK together) p 1 + p 2 =p 1,2 m 1 v 1 + m 2 v 2 =(m 1 + m 2 )v

7. Elastic Collisions: (2 objects collide and BOUNCE apart) p 1 + p 2 =p 1 ' + p 2 ' m 1 v 1 + m 2 v 2 =m 1 v 1 ' + m 2 v 2 '
