Hello Friends,
You have ONE HOUR to complete this assessment.
It assesses three standards:

System: Draw a system schema.
Force 1: Newton's First Law, inertia, mass, weight, balanced and unbalanced forces
Force 3: Free Body Diagrams

Watch this video of bamboo being unloaded from a truck in Taiwan. Think of the video as having two parts: Part I is about 30second long. Part II is the remainder of the video.
Using the vocabulary and concepts of Newton's First Law, explain how the driver is using the First Law to his advantage to unload the bamboo. Your explanation should deal with the two parts of the video separately.

If an air hockey puck was sliding across a table, would the free body diagram below be valid?
* Assume no friction or air resistance.

1) Draw a system schema for the situation.
2) Add or remove any force vectors to the force diagram given so that it accurately represents the forces on the object.
3) Label all forces by type.
