Introduction:

In this lab you will use Pearson's "ActivPhysics Online" simulations and questions.  This is a useful, interactive resource, pretty well done, for studying many physics topics.  If you ever want to find it later for help with any physics topic, just google "activphysics."

These are designed to make you interact, answer questions, solve problems, and get more information.  I would like you to go through two required sections completely, and look briefly at a third.  I would like you to work in groups to foster discussion and sharing of the ideas.

Lab Report:

Please record your answers and calculations for each question on paper.  A separate lab report is not required, just your written notes showing that you went through each step.  Each person will submit these notes/answers by monday.  If you don't finish in lab, you may finish at home.

Required Sections:

FIRST:
6.2 Collisions and Elasticity
    Complete entire section, answering all questions;  if your computer will allow it, don't forget to listen to the audio at the top and the video at the bottom.

SECOND:
6.10 Pendulum Person-Projectile Bowling
    This is basically a compound-part problem to solve, using collisions and energy concepts.   Make sure to actually solve the problem, showing equations and calculations like you would on a HW problem.

THIRD:
6.5 Car Collision: Two Dimensions
    You do NOT have to solve all three problems.  Instead, discuss what physics governs each collision, and play with the elasticity slider. 
    Answer this question after you've experimented with the simulation:  
        If you are unfortunate to be in this type of car crash, would you rather have a high or low elasticity?  Explain your answer.
  

Optional:

    If you'd like to experiment with more of these (in section 6), feel free.  They're all good practice/reinforcement.  If you do explore others, feel free to list them, with brief notes/key ideas, at the bottom of your lab notes.
