π’ 6: W 1/27, π΅ 8: Th 1/28 friction and vector forces
π’ 6: W 1/27, π΅ 8: Th 1/28 friction and vector forces
Today, we'll look at one other kind of problem - we pull or push a block at an angle. We'll see that when we do this, the normal force is NOT equal to the force of gravity! We'll try to finish Friction & Vector Forces during class.
Homework: Finish Friction & Vector Forces. (SOLUTIONS)
π© 6: Th 1/28, π¦ 8: F 1/29 relative motion / boats
π© 6: Th 1/28, π¦ 8: F 1/29 relative motion / boats
Today, we'll use this simulation to explore the concept of relative motion. We'll observe a model of relative motion in class, and then we will try to come up with a mathematical model (formula) to describe relative motion. We will learn how we can use our knowledge of vectors to determine the velocity of one object relative to another in two dimensions. We will convince ourselves of the independence of x- and y- components.

Homework: Quiz next class on β Positive Physics: unit 9 - inclined forces. Watch the following videos on relative motion:
π 6: M 2/1, π 8: M 2/1
