1. Free Body Diagrams

2. Which of these situations has a normal force?
Warm-up
Which of these situations has a normal force?
What is the normal force equal too?

3. A free body diagram is pictorial representation of all the forces acting on an object.
We will be using all those notations to denote which force is acting on the object. Each one could have multiple forces acting on it.

4. Draw a free body diagram for the situation. Use a dot diagram.

5. Draw a free body diagram for the situation. Use a dot diagram
Draw a free body diagram for the situation. Use a dot diagram. (air resistance is negligible)

6. Draw a free body diagram for the situation. Use a dot diagram
Draw a free body diagram for the situation. Use a dot diagram. (air resistance is negligible)

7. Draw a free body diagram for the situation. Use a dot diagram.

8. Draw a free body diagram for the situation. Use a dot diagram.

9. Draw a free body diagram for the situation. Use a dot diagram.

10. Draw a free body diagram for the forces acting on the suitcase
Draw a free body diagram for the forces acting on the suitcase. Do not ignore friction (air resistance is negligible)

11. Draw a free body diagram for the forces acting on the wagon
Draw a free body diagram for the forces acting on the wagon. Do not ignore friction (air resistance is negligible)
