Here's some bantha fodder for your notecard!

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'

Momentum = Inertia in Motion

p = mv

Impulse = Change In Momentum

I = Δp = (pf - pi)

Ft = Δmv = m(vf - vi)

pbefore = pafter

MOMENTUM IS CONSERVED!!!

(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!!!

(2 objects collide and STICKtogether)

p1 + p2 = p1,2

m1v1 + m2v2 = (m1 + m2)v

(2 objects collide and BOUNCEapart)

p1 + p2 = p1' + p2'

m1v1 + m2v2 = m1v1' + m2v2'
