The total momentum before a collision is _________ the total momentum after a collision.

It depends on the type of collision

When is momentum conserved in a collision?

When the collision is inelastic.

When the collision is inelastic OR elastic but never an explosion.

Extending the time of a collision allows you to...

change the impulse of the collision.

Which object listed below has the greatest momentum?

A 0.4 kg object rolling at 2 m/s.

A 0.05 kg object rolling at 0.2 m/s.

A 0.15 kg object rolling at 2 m/s.

A 0.15 kg object rolling at 1 m/s

The law of conservation of momentum states that,

p before is the same as p after

When the speed of an object is doubled, its momentum

remains unchanged in accord with the conservation of momentum.

In this type of collision, objects tend to "stick" together.

They "stick" together in both types of collisions

A 10kg toy truck moves at 5m/s East. It collides and bounces off of a 5kg toy car moving 10 m/s moving west. Which equation would you use to solve for the final velocity of the car?

m 1 v 1i +m 2 v 2i =m 1 v 1f +m 2 v 2f

(m 1 +m 2) v i =m 1 v 1f +m 2 v 2f

m 1 v 1i +m 2 v 2 i =(m 1 +m 2 )v f

What is the formula for an explosion?

m 1 v 1i + m 2 v 2i = m 1 v 1f + m 2 v 2f

m 1 v 1 + m 2 v 2 = (m 1 + m 2 )v f

(m 1 v 1 )(m 2 v 2 ) = (m 1 )v f
