CLASSWORK
Acceleration Lab Work-time (30 min)
- Labs are due Tuesday by the beginning of class, via Google Docs share with Mr. A
Practice Problems

Practice for Acceleration Written Test
- We will have the acceleration written test next Tuesday.
- The test will include 5-7 problems, as well as 5-6 reading related questions. I will also ask you to define the rules of free-fall and terms like "acceleration".
- Today is the last chance to solve practice problems with Mr Alexander.
- Individually, practice by solving the following problems:
Chapter 3, Page 81, # 80, 81, 82, 85, 90, 92, 100, 102, 110
- Prep for Exam:
Equation sheet is allowed (equations only)
1/2 sheet of notes allowed
HomeWORK
Complete the practice problems (2, 3, 11, 12) for HW
GOALS: SWBAT...
1. Define Force
2. Draw FBD's with vectors (arrows) of correct (proportional) length
3. Describe the two scenarios possible when Fnet is zero
WARM-UP: Free Body Diagram (FBD)
Draw an FBD for the following scenario: Blimp Photo
The Goodyear blimp is taking off for a flight. It is accelerating to the east (right) and climbing at an increasing rate.
Draw force vectors showing the magnitude and direction of each force the blimp is experiencing.
Show the appropriate magnitude
CLASSWORK:
1. READING QUIZ: (topic: pg 96-98)
- postponed until Wednesday
2. Notes
Inertia, Net Force, Newton’s Laws Notes (pt.2)
Inertia: recall that inertia is the tendency for an object to resist a change in state of motion (aka, to resist an acceleration)
1. 0:48 What is the definition of Force?
2. 1:11 Draw an FBD showing the forces on the block
3. 1:27 What is the effect of an increase of applied force?
4. 1:50 How does Mr. P increase the blocks inertia?
What is the effect of an increase in inertia?
5. 2:42 Why doesn't force always cause an acceleration?
6. 4:33 Force Types: Are these contact or field forces?
a. Jumping from a tree (gravity)
b. Braking a car (friction)
3. Practice:
Complete Pg 112: 40-43
4. More notes...
What is the motion of an object with no net force acting on it?
Answer... (there are two options)
1. 0:31 Define Newton's 1st law
2. 2:18 How does Mrs. Zeller's FBD show that there is no net force on the rock? Copy her sum of forces equation.
3. 2:18 In the rock example, the rock is at rest. Does that mean there are no forces on the rock? If not, what does it mean?
4. 2:51 In the ball bearing example, the ball bearing is moving. Does that mean there is a net force on the ball? If not, what does it mean?
5. Practice Problems

6. Check for Understanding
