π’ 6: M 3/22, π΅ 8: T 3/23 conservation of momentum
Today, weβll first discuss how we a system with no impulse will conserve momentum. We'll start by exploring momentum conservation in "explosions." Then, we'll continue to discuss elastic and inelastic collisions and then do a few problems. Remember that momentum is conserved in all collisions, but energy is only conserved in elastic collisions. Also remember that in a collision between two objects, each of the objects experiences an equal impulse (the momentum equivalent to Newton's 3rd Law).
Presentation: Collisions (we'll do some sample problems found here)
Homework: Do problems from β Positive Physics unit 14: momentum "work" problems from the following sections only:
conservation of momentum - 18 quick problems
Finish these problems by Thursday at 10pm. Only completion score counts. No late work will be accepted.

If you need extra support on today's lesson or if you missed today's lesson for any reason, check out the following videos which could be helpful in catching you up on understanding collisions.
In the following video, the chart is a useful method, but if you'd rather express the conservation of momentum as an equation like we did conservation of energy, that would be acceptable and probably faster. Focus on understanding the concepts of momentum conservation here.
Below is an example of how to solve a perfectly inelastic collision the equation way, which is preferred over the chart method.
