This week we learned about collisions and momentum conservation. This definition comes from the Physics Classroom site.
For a collision occurring between object 1 and object 2 in an isolated system,
the total momentum of the two objects before the collision is equal to
the total momentum of the two objects after the collision. That is, the
momentum lost by object 1 is equal to the momentum gained by object 2. An isolated system is one where no outside forces act.
There are two types of collisions:
Elastic: where the objects bounce off each other.
Inelastic: where the objects stick together.
There will be a test next week: Wed. Jan. 28 (Section A), Thur. Jan. 29 (Section B and D).
There are review questions and solutions on the Documents Tab.
