GOALS: SWBAT...
1. Define Inertia & Equilibrium
2. Recite the symbols and definitions for the six common types of forces
3. Use Newton's Laws to solve problems
4. Classify forces according to the agents that cause them
WARM-UP & Homework check
Watch Mr. A roll the aluminum cans (one full, one empty) across the flat table into the static paper cups.
1. The cans rolls at equal speeds, and hit cups of equal mass at equal speeds.
A. What is different about the two collisions?
B. Why are the collisions different?
2. What is the term that describes the tendency of an object to resist change?
3. Lets assume the ball bearing rolls at a constant velocity. What does that say about the forces acting on the object?
4. If Nathan buys a dozen cupcakes for $4, and sells them all for $1 each, what is his net gain, or profit? Based on this question, what does the term "net" mean?
CLASSWORK
1. Review of FBD homework
2. Inertia Notes
A. What does the phrase, “state of motion” mean?
B. Write a mathematical equation for the “change in the state of motion.”
C. Define “mass” in terms of inertia.
D. Redefine “mass” in terms of acceleration.
E. Which object that Marcia pushes will be harder to move? Which has greater inertia?
3. Stump the Chump
This is a reading game, meaning you will need to read to be successful. Let's review, what do you need to do to be successful? READING!
Goals: You'll be able to recognize symbols describing forces, define forces based on their symbol, describe Newton's 1st & 2nd laws, and define vocab terms
Instructions: Individually, Read pg 92-97. While reading, create:
one question for pg 92,
one for 93,
two for 94,
two for 95,
two total for pg's 96 & 97
Homework
Reading & Problem Solving Quiz: pg 92-97. Know your vocab. Know the symbols and definitions listed in Table 4-2.
I will check your inertia notes and Stump the Chump questions Monday.
WARM-UP:
Use pages 100-101 to solve the following problems
1. Copy the definition, then write the term that matches the definition
"The force exerted by a fluid on an object moving through the fluid"
2. What are two common examples of fluids that cause this force?
3. "The constant velocity that's reached when when the drag force
equals the force of gravity"
4. Choose two sports-related balls (baseball, etc). Which would have a
higher terminal velocity? Why?
