Here's some bantha fodder

for your notecard!

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 negative sign just shows

direction!!!

The two objects have EQUAL and

OPPOSITE Momentums.

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

'

For ALL Collisions/Separations: pbefore = pafter

MOMENTUM IS CONSERVED!!!
