AP Physics 2: Algebra-Based questions with worked answers

These 8 questions are printed in full on this page and are drawn across all 7 course units. Nothing here is generated on the fly. Cover the options, solve each one on paper, and only then open the worked answer to compare your method with the one shown.

Question 1: Two moles of an ideal gas occupy 0.05 m^3 at 300 K. What is the pressure? Use R = 8.314 J per mol per K.

AP Physics 2: Algebra-Based · Thermodynamics

  1. about 1.0 x 10^5 Pa
  2. about 5.0 x 10^4 Pa
  3. about 2.5 x 10^5 Pa
  4. about 1.0 x 10^3 Pa
Show the worked answer
  1. Rearrange the ideal gas law to P = nRT / V.
  2. nRT = 2 x 8.314 x 300 = 4,988.4 J.
  3. Divide by the volume: 4,988.4 / 0.05.
  4. That is 99,768 Pa, or about 1.0 x 10^5 Pa, close to normal air pressure.

Answer: about 1.0 x 10^5 Pa

Question 2: Two charges of 2 microcoulombs each sit 0.3 m apart. What is the force between them? Use k = 8.99 x 10^9.

AP Physics 2: Algebra-Based · Electric Force, Field, and Potential

  1. 0.40 N
  2. 0.12 N
  3. 4.0 N
  4. 0.04 N
Show the worked answer
  1. Coulomb's law is k times the product of the charges divided by the distance squared.
  2. The charge product is 2 x 10^-6 times 2 x 10^-6 = 4 x 10^-12.
  3. The distance squared is 0.3^2 = 0.09.
  4. 8.99 x 10^9 x 4 x 10^-12 / 0.09 = 0.40 N, and it is repulsive for like charges.

Answer: 0.40 N

Question 3: Two 6 ohm resistors are connected in parallel across a 12 V battery. What is the total current?

AP Physics 2: Algebra-Based · Electric Circuits

  1. 4 A
  2. 1 A
  3. 2 A
  4. 8 A
Show the worked answer
  1. For two equal resistors in parallel, the total resistance is half of one of them.
  2. 6 / 2 = 3 ohms.
  3. Ohm's law gives current = voltage / resistance.
  4. 12 / 3 = 4 A.

Answer: 4 A

Question 4: An electron moves at 2 x 10^6 m/s perpendicular to a 0.5 T field. What is the magnetic force on it? Use q = 1.6 x 10^-19 C.

AP Physics 2: Algebra-Based · Magnetism and Electromagnetism

  1. 1.6 x 10^-13 N
  2. 1.6 x 10^-19 N
  3. 3.2 x 10^-13 N
  4. 8.0 x 10^-14 N
Show the worked answer
  1. The magnetic force is qvB when the velocity is perpendicular to the field.
  2. q times v = 1.6 x 10^-19 x 2 x 10^6 = 3.2 x 10^-13.
  3. Multiply by B = 0.5.
  4. 3.2 x 10^-13 x 0.5 = 1.6 x 10^-13 N.

Answer: 1.6 x 10^-13 N

Question 5: An object sits 15 cm from a converging lens of focal length 10 cm. Where is the image and what is the magnification?

AP Physics 2: Algebra-Based · Geometric Optics

  1. 30 cm on the far side, magnification -2
  2. 6 cm on the far side, magnification -0.4
  3. 30 cm on the same side, magnification +2
  4. 25 cm on the far side, magnification -1.67
Show the worked answer
  1. Use the thin lens equation: 1/f = 1/do + 1/di.
  2. 1/di = 1/10 - 1/15. A common denominator of 30 gives 3/30 - 2/30 = 1/30.
  3. So di = 30 cm, positive, which means a real image on the far side.
  4. Magnification is -di / do = -30 / 15 = -2, so the image is twice as large and inverted.

Answer: 30 cm on the far side, magnification -2

Question 6: A sound wave travels at 340 m/s with a frequency of 680 Hz. What is its wavelength?

AP Physics 2: Algebra-Based · Waves, Sound, and Physical Optics

  1. 0.5 m
  2. 2.0 m
  3. 0.2 m
  4. 231,200 m
Show the worked answer
  1. The wave equation is speed = frequency times wavelength.
  2. Rearrange to wavelength = speed / frequency.
  3. 340 / 680 = 0.5.
  4. So the wavelength is 0.5 m.

Answer: 0.5 m

Question 7: What is the energy of a photon with a wavelength of 500 nm? Use the shortcut E in eV = 1240 divided by the wavelength in nm.

AP Physics 2: Algebra-Based · Modern Physics

  1. 2.48 eV
  2. 0.40 eV
  3. 4.13 eV
  4. 620 eV
Show the worked answer
  1. The shortcut avoids converting to joules: E = 1240 / wavelength in nanometers.
  2. The wavelength is 500 nm.
  3. 1240 / 500 = 2.48.
  4. So the photon carries 2.48 eV, which is visible green light.

Answer: 2.48 eV

Question 8: A sealed rigid container of gas is heated from 300 K to 600 K. What happens to its pressure?

AP Physics 2: Algebra-Based · Thermodynamics

  1. It doubles.
  2. It stays the same.
  3. It is cut in half.
  4. It goes up four times.
Show the worked answer
  1. A rigid container means the volume cannot change, and sealed means the moles stay fixed.
  2. The ideal gas law then makes pressure proportional to temperature in kelvin.
  3. The temperature goes from 300 K to 600 K, a factor of 2.
  4. So the pressure also doubles.

Answer: It doubles.

How the generated AP Physics 2: Algebra-Based sets are created

The 8 questions above are fixed and checked. The generator at the top of the page is different: it writes fresh questions with AI from the course and unit information shown here, then the application checks each one for a complete prompt, four choices, one keyed answer, and an explanation. Generated questions are original practice—not official or released exam questions—and AI can still make mathematical mistakes. Verify a disputed answer with the stated method, your course materials, or the MathGPT solver, and follow the site's academic-integrity guidance.
