Chapter 7: Overview of AP Physics Concepts
The College Board has identified seven strands of "Big Idea" that are the central organizing structure for the AP Physics 1 and AP Physics 2 exams.
The tests try to reinforce the central ideas in ways that are appropriate to the subject matter.
Mass and charge are some of the properties of objects and systems.
When studying for the tests, use the Big Idea strands as a guide.
The conceptual questions may appear on the exam.
An isolated mass is being acted upon by outside forces.
The object's internal structure is ignored.
The object is defined by its mass and charge.
It doesn't make sense to use thermal energy or the conserved quantities for a single object being analyzed.
A system is made up of objects that can interact.
The potential energy of relationship between interacting objects, the heat capacity of the parts, and the conserved quantities are useful concepts.
Make sure you have a manageable study schedule in advance of the exam.
Make sure you are familiar with the exam format and memorize all units.
Multiple-choice questions don't have a penalty for wrong answers, so don't skip any.
Write your answers clearly.
Make sure you have a #2 pencil and bubble in your answers on multiple-choice questions.
Short-answer questions should be written in full sentences.
Use best-fit lines or curves to label graphs.
The "Seven Big ideas" of physics are defined by the College Board as helpful clues as to what key concepts are emphasized on the exam.
A single mass can be used to represent an object.
It is best modeled as experiencing changes in speed and direction when exposed to external forces.
A system is a group of objects that are isolated.
Relax and do the practice tests.
Review the concepts in the chapter questions.
Before the exam, get a good night's sleep.
On the day of the exam, bring all registration materials with you, as well as pens, pencils, calculators, extra batteries, and a metric ruler.
