Physical Science:
Momentum-
Will and I reviewed his vocabulary words. I then added a few new words for this unit. Starting with momentum and collision. We discussed the units used to measure Force, Mass, Velocity, Speed, Weight, and Acceleration before adding the unit for Momentum. We discussed what would happen if a train, with no brakes, suddenly ran out of fuel. I explained that the momentum of the train would carry the train along the track for a while, and how far it traveled depended on the mass of the train and how fast it was traveling before the fuel ran dry. The formula for Momentum is mass times velocity p=mv). We worked several situations, where the mass and speed of an object were known, to determine the force and/or the momentum. We compared the processes used to determine force and momentum to find the subtle differences between the two. Homework: Review vocabulary words for the test this week.
