Unit 8


Students will begin unit 8 by defining impulse and looking at the relationship between force and time. Then we will explore the relationship to velocity and mass in laboratory. Students will use the results of the lab to define momentum. Students will then explore the properties of momentum transfer in laboratory through basic collisions. We will then expand this concept to include 2D collisions and real life applications.  Momentum video on you tube.
 

Readings/Notes/Powerpoints:
Glencoe book:  Physics:  Principles and Problems

Suggested reading:  Pages 229-245  This reading covers how a force applied for a period of time (impulse) can alter an objects momentum.  It also demonstrates how momentum is transferred by bouncing, hit an stick, and explosive interactions.  Finally this reading explains how momentum is transferred in two dimensional collisions.

Collision Carts-test remediation
Pick a cart, put it on a track and slam it into a second cart. Change the mass and/or the velocity and repeat the experiment. Put two carts next to each other on the same track with a firecracker between them, Ignite the fuse and watch the carts fly apart when the firecracker explodes. Do all this and more without getting yelled at by your physics teacher or sent to the deans office for possession of incendiary devices. What a blast!
