What are the 2 main points of Newton’s 1st Law
“Forces” is not enough to explain why an object changes its motion. What do we need to add?
Why do architects draw blueprints before building a house?
What does the term 2-Dimensional mean?

4. Drawing Pictures & Free Body Diagrams
If I describe the forces on an object, how do we know if it is moving?
If I describe the forces on an object, how do we know if it is a rest?
We need to be able to represent these words in picture form!

5. Drawing Pictures & Free Body Diagrams
A ball is a rest on a table
Normal Force(FN)
Force of Gravity (FG)

6. Drawing Pictures & Free Body Diagrams
A book is pushed across a flat table
Normal Force(FN)
Applied Force (FA)
Friction Force (Ff)
Force of Gravity (FG)

7. Drawing Pictures & Free Body Diagrams
Identify the object you will draw a diagram for
Identify all the forces acting directly on the object
Draw a dot, square, circle to represent the object of interest
Draw an arrow to represent each force & label each force arrow
Arrows should show magnitude of force as well (how large)
If the object is stationary or is moving at a constant speed, the net force should be zero. 
If the object’s motion is changing, the net force should be in the direction of the change.
