The AP Physics 2: Algebra-Based exam is a comprehensive assessment of second-year, college-level physics concepts that extend beyond the mechanics-focused AP Physics 1. This 3-hour exam evaluates a student's mastery of foundational principles in fluid statics and dynamics, thermodynamics, electricity and magnetism, optics, and modern physics, including quantum and nuclear phenomena. It is designed for students who have successfully completed a first-year physics course and wish to deepen their understanding of the physical world. The exam emphasizes conceptual reasoning, quantitative problem-solving using algebra and trigonometry, and the ability to design and analyze experiments. Success on the exam demonstrates a robust ability to connect multiple big ideas across physics, such as conservation laws, fields, and force interactions. A qualifying score can earn college credit and placement, allowing students to advance in their STEM academic or career pathways.

A hydrogen atom emits visible light when an electron falls from a higher energy level to n = 2. A student compares this with an electron falling to n = 1. Which transition would emit the higher-energy photon? Which option is best?
A positive test charge is moved slowly from point A to point B in a region where the electric potential at B is higher than at A. The path winds around a metal support, but the electrostatic field is unchanged. Which energy statement is correct? Which option is best?
A metal bar slides to the right on conducting rails in a uniform magnetic field into the page. The rails are connected through a resistor. The bar length and speed are measured twice, but the resistor's paint band is partly scratched. Which change would double the motional emf? Which option is best?
A portable speaker uses two identical resistors that can be connected either in series or in parallel across the same battery. The battery warms more in one arrangement. Which comparison is correct for ideal resistors? Which option is best?
A student maps equipotential lines between two irregular metal electrodes on conducting paper. Near one sharp electrode tip, the equipotential lines are very close together; near a broad flat edge they are farther apart. Which inference is best? Which option is best?
