1. 2*6 Newton’s 3rd Law: Run and Jump
WDYS? (p198) /
WDYT? (p198)
I would teach/instruct someone who has NEVER jumped before to do _____.

2. 2*6 Investigate A (p )
What happens when an object pushes/pulls on another object???
Your motion is accelerated when _____. The direction of acceleration is _____ from the wall.
Your motion is constant speed when _____. Without friction, you should travel _____.
The source of the force is _____ and its direction is _____ the wall.
You push on the _____ and its direction is _____ the wall.
The forces are _____ but _____!!!!!!!!!

3. 2*6 Investigate B (p200)
Draw the free-body diagram of table-book AND hand-book
Set up meter stick, books, and weight
_____ happens!!!
a) The more weight that is added to the meter stick, the _____ the bend.
b) skip
c) The meter stick (does/does not) bend with the coin.
d) draw a free-body diagram of the demo and make sure to label the arrows

4. ***you cannot touch someone without someone touching you back***
2*6 Notes
Pushing or Pulling Back
Acceleration and force act in SAME direction (directly)
Acceleration and mass work in OPPOSITE direction (indirect)
Newton’s 3rd Law  for every force, there is an equal and opposite force, where forces ALWAYS come in pairs where the 2 forces always act on different objects
EXAMPLE Student pushed (applied a force) on wall and wall pushed back on student
***you cannot touch someone without someone touching you back***

5. 2*6 Notes 2. Inanimate Objects CAN Push Back
The belief that a wall/floor/door/table can apply a force is troublesome 
BUT the masses on the meter stick provided evidence of how an inanimate object CAN apply a force
The BEND provides a FORCE as shown by the free-body diagram 

6. 2*6 Notes 3. Drawing Free-Body Diagrams
Free-Body Diagrams  are used to show relative strength and direction of all forces acting on an object
Each force is represented by an arrow and demonstrates balanced (not moving) or unbalanced (moving) objects
The direction of the arrow is the direction of the force
The size of the arrow is the strength of the force
The arrows usually stems from the Center of Mass  point at which all object’s mass is concentrated

7. 2*6 Notes
4. Challenging Newton’s 3rd Law
Draw the Free-Body of you pulling a desk chair across the floor.
