Solving complex linear momentum problems that are elastic and the two final speeds are not known.

Today we are working on the problem package and learning how to solve some more complex problems.
Conservation of Linear Momentum InvestigationToday you will go online and use the online applet provided to investigate the momentum changes that occur when two (or more) objects collide with one another.
You can get to the applet from: Online Collision Applet Extension on Momentum-Impulse TheoremToday we are finishing up the worksheets that were handed out on Friday and starting an extension of the theorem using Integral Calculus. For more information click here. Example: if the time-variant force is F(t) = t^2+2t+6 and you want to know the impulse (momentum change from t=1 to t=4 seconds we must integrate F(t) from 1 to 4 Notice that the area from 1 to 4 is the impulse. You can estimate it right from the graph without even doing the "calculus."
Momentum-Impulse Theorem
Today we will do a short lesson about the basics of momentum. What is it? How can it be calculated?
Dynamics in 2DOver the next few days we will be working on the following sheets (examples and problem sets). This will lead up to the test evaluation for this mini-review-unit.
Today is the projectile motion competition launch day. I will post details about the angles and distances launched as well as videos from the launches after they are completed.
