# AP Physics B

AP Physics B is an Advanced Placement science course in which high school students study Newtonian mechanics, electricity and magnetism, fluid mechanics and thermal physics, waves and optics, and atomic and nuclear physics in preparation for a cumulative exam given each May. The course is non-calculus-based and involves algebra and trigonometry to solve various physics problems. It is supposed to be equivalent to a year-long introductory college course in physics.[1]

This course can also help prepare students for the SAT Subject Test in Physics which is also administered by College Board.

This course is scheduled for discontinuation and replacement with AP Physics 1 and AP Physics 2 beginning in the 2014–2015 school year. The last administration of the AP Physics B exam was in May 2014.

## Exam

The exam is divided into two sections, a multiple choice section (70 questions) and a free response section (6–7 questions).[2] Each section must be completed within 90 minutes. In order to test knowledge as well as skills, the multiple choice section is taken without a calculator. The free response section permits the use of a calculator as well as a list of common formulas. The scoring is weighted such that each section is worth fifty percent of the final score. Overall, the exam is configured to approximately cover a set percentage of each of the five target categories:[3]

Topic Percent
Newtonian Mechanics 35%
Fluid Mechanics and Thermal Physics 15%
Electricity and Magnetism 25%
Waves and Optics 15%
Atomic and Nuclear Physics 10%

## Purpose

According to the College Board web site, "the Physics B course provides a foundation in physics for students in the life sciences, premedicine, and some applied sciences, as well as other fields not directly related to science."[4]

The grade distributions for the Physics B scores since 2010 are as follows:

Score 2010[5] 2011[6] 2012[7] 2013[8] 2014[9]
5 14.8% 16.4% 16.3% 16.6% 14.3%
4 18.5% 19.2% 19.3% 19.9% 18.5%
3 26.1% 25.9% 26.4% 26.1% 26.9%
2 18.6% 17.3% 16.8% 16.3% 17.5%
1 21.9% 21.3% 21.3% 21.1% 22.8%
Mean 2.86 2.92 2.93 2.95 2.84
Number of Students 67,312 75,648 80,584 89,263

## Redesign

Starting in the 2014–2015 school year, AP Physics B will no longer be offered, and AP Physics 1 and AP Physics 2 will take its place. Like AP Physics B, both will be algebra-based, and both will be designed to be taught as year-long courses.[10]
