1 Complete the table below.

 Force's name When is the drawn on the the diagram and what direction does it point? Formula/Other notes Friction Normal Tension Weight Net Force
2

Draw the free body diagram for the box when is is being pulled by the rope across a rough surface at a constant velocity.

3

A box is sliding across a rough textured floor. Draw what you think the free body diagram would look like. (The term "rough surface" is geek speak telling you to account for the frictional force.)

4

Draw the free body diagram for the box along the incline this incline is "perfectly smooth." The box is accelerating down the incline even though the rope is taught. (The term "perfeclty smooth" or "smooth" is geek speak telling you that the surface is frictionless.)

5

What must you have if you have a normal force?

6 What must you have if you have a tension force?
7 What must you have if you have a weight?
8 Draw a free body diagram of all the forces acting on the box if it is not moving but the rope is being pulled gently.

9 If a body is accelerating, then what force must be indicated on the free body diagram?
10 Draw a free body diagram for both of the boxes shown below.

11 Create two equations for the given free body diagram.

12 Create two equations for the given free body diagram.

13 Create two equations for the given free body diagram.

14 Create two equations for the given free body diagram.
