Day 6: Force Diagrams and Net Force

FQ:  How do free body diagrams connect to N1L and N2L?

1. Demo:  Normal Force 

    Do things really push back? (Ruler bridge + bathroom scales, shifting weight)

2.  Watch:  FBD

Watch this video to review force diagrams. 

More than one force can act on an object at a time. The forces can push or
pull in any direction. What happens to the object when the forces act
depends on two things:
→ How strong the forces are
→ The direction of the forces
When more than one force acts on an object, the forces combine to form a
net force. The combination of all the forces acting on an object is the net
force.

3.  Concept Builder:  Balanced and Unbalanced Forces

4.  Project: Force Diagram 

     Answer question #8 to create a force diagram for something falling in your sport.

5:  Practice!

Optional:  Are N3L forces the same as balanced forces?
