Today, we began class with the postgame analysis where we took several steps to find the various characteristics of a velocity vs. time graph.
- If signs of velocity and acceleration are the same: then the object is speeding up
- If signs of velocity and acceleration are different: then the object is slowing down

Then, we performed the Motion Analysis: Falling Objects lab in which we dropped blocks of wood with different masses, and measured their slopes using video analysis to determine acceleration due to gravity.

Afterwards, we had our kinematics test in which we had to apply all of the new equations we learned yesterday.
Next, we were introduced to the KOTH project:

Lastly, we finished off the day by watching an installment of Elegant Universe

Real World Connection:
Mouse traps are set by pulling back the lever, which gives it a ton of potential energy. When the trap is triggered by an object putting weight on it, all that potential energy turns into kinetic energy which has the power to easily kill a mouse.
