# Summer Assignment

The goals of the summer assignment are:

1. To remind you of the math that you'll need for AP Physics.
2. To expose you to a couple of new types of problem that you may not be used to yet.  (In a perfect world, you would struggle with them a little but figure them out.  In an imperfect world, you might struggle a lot and get help from me.)
3. To get you started thinking about problem solving and designing experiments.
4. To weed out anyone who's not serious about putting effort into the class.

# Laboratory

#### Notes pp. 13-42

Laboratory safety, style guides and rubrics for laboratory notebooks and formal reports, laboratory equipment, performing experiments.

The purpose of this chapter is to teach skills necessary for designing and carrying out laboratory experiments, recording data, and writing summaries of the experiment in different formats.

• Designing & Performing Experiments discusses strategies for coming up with your own experiments and carrying them out.
• Accuracy & PrecisionUncertainty & Error Analysis, and Recording and Analyzing Data discuss techniques for working with the measurements taken during laboratory experiments.
• Keeping a Laboratory Notebook and Formal Laboratory Reports discuss ways in which you might communicate (write up) your laboratory experiments.

Calculating uncertainty (instead of relying on significant figures) is a new and challenging skill that will be used in lab write-ups throughout the year.

### Skills learned & applied in this topic:

• Designing laboratory experiments
• Error analysis (calculation & propagation of uncertainty)

# Dynamics (Forces) & Gravitation

#### Notes pp. 103-139

In this chapter you will learn about different kinds of forces and how they relate.

• Newton's Laws and Forces describe basic scientific principles of how objects affect each other.
• Free-Body Diagrams describes a way of drawing a picture that represents forces acting on an object.
• Forces Applied at an Angle, Ramp Problems, and Pulleys & Tension describe some common situations involving forces and how to calculate the forces involved.
• Friction and Aerodynamic Drag describe situations in which a force is created by the action of another force.
• Newton's Law of Universal Gravitation describes how to calculate the force of gravity caused by massive objects such as planets and stars.

One of the first challenges will be working with variables that have subscripts.  Each type of force uses the variable F.  Subscripts will be used to keep track of the different kinds of forces.  This chapter also makes extensive use of vectors.

Another challenge in this chapter will be to "chain” equations together to solve problems.  This involves finding the equation that has the quantity you need, and then using a second equation to find the quantity that you are missing from the first equation.
