Today's lesson in class was based on a new unit – Momentum.
It incorporated the previous unit on force, as force is one of the variables in
the equations that solve for momentum. We did a lab activity that involved
pushing two carts toward each other with a bouncing mechanism on a frictionless
surface. During this lab, I observed that the faster one cart was going, the
more force transferred to the slower cart, leaving the initially fast car move
really slow. This reminded me of the action movies I love so much. The overly
dramatized fighting scenes often show two people running toward each other in
order to fight. One person runs at a higher velocity, and it is the person that
is running faster that transfers his force to his opponent. This person staggers
back a couple steps while the opponent goes flying out of the screen.
