Tuesday:

Types of Collisions
Momentum & The law of conservation of momentum
PASCO CARTS: focus on conservation
Elastic
- Three types of collisions
- Phrase in terms of giving momentum to the other
Totally inelastic
- Can you get them to collide & stop?
- What about different weights?
Could a mac truck and a roller skate have the same momentum? How?

Momentum numbers (already multiplied)
Don’t do it as long algebra; simply have boxes and box for total before & after.
Totally Inelastic – find total; which way do they go?
Elastic – find total, solve for missing one
Point about bouncing (give three identical, but first object goes forward, sticks, goes back)
What kinds of collisions transfer the most momentum?
