We covered Projectile motion, Newton's 3rd Law of Motion and centripetal forces in the Powerpoint on "Forces".  At the conclusion of the notes, students were given a "Momentum" word problem worksheet (20 pts) to calculate momentum, mass or velocity.  They were also given a "Forces" Crossword Puzzle (20 pts) to complete for homework.  They will have the Forces Vocabulary Test tomorrow.

We defined and described where "gravity" comes from, the forces on stationary objects, how an object can be balanced or unbalanced, the "Law of Universal Gravitation", and the differences in mass and weight.  We concluded class with a worksheet on how to calculate the weight of an object. The "Weight" Word Problem WS was worth 30 pts.  They will have the Forces Voc. Test on Thursday and Forces Ch. Test on Friday.
