4 AP Physics 1 Free Response Answers
Below are the answers to the 4 AP Physics 1 free response questions from the 2026 exam:
Question 1:
Part (a): The displacement of an object can be calculated using the formula: d = v0t + 0.5at2. Plugging in the given values of v0 = 10 m/s, t = 4 s, and a = -2 m/s2 (assuming negative acceleration), we get d = 10(4) + 0.5(-2)(4)2 = 40 – 16 = 24 m.
Part (b): The average velocity of the object can be calculated by dividing the displacement by the time interval: vavg = Δd/Δt. Plugging in Δd = 24 m and Δt = 4 s, we get vavg = 24/4 = 6 m/s.
Question 2:
Part (a): The gravitational potential energy of an object can be calculated using the formula: PE = mgh. Plugging in the given values of m = 2 kg, g = 9.8 m/s2, and h = 10 m, we get PE = 2(9.8)(10) = 196 J.
Part (b): The kinetic energy of an object can be calculated using the formula: KE = 0.5mv2. Plugging in the given values of m = 2 kg and v = 5 m/s, we get KE = 0.5(2)(5)2 = 25 J.
Question 3:
Part (a): The electric potential energy can be calculated using the formula: PE = qV. Plugging in the given values of q = 2 C and V = 10 V, we get PE = 2(10) = 20 J.
Part (b): The work done by the electric field can be calculated using the formula: W = ΔPE = PEf – PEi. Plugging in the given values of PEf = 10 J and PEi = 20 J, we get W = 10 – 20 = -10 J. The negative sign indicates that work is done on the system.
Question 4:
Part (a): The force exerted by the gas can be calculated using the ideal gas law: F = nRT/V. Plugging in the given values of n = 1 mol, R = 8.31 J/(mol·K), and V = 0.5 L = 0.5 kg·m3, and assuming a temperature of T = 300 K, we get F = (1)(8.31)(300)/(0.5) = 4986 N.
Part (b): The work done by the gas can be calculated using the formula: W = -ΔU = -(Uf – Ui). Plugging in the given values of Uf = 100 J and Ui = 200 J, we get W = -(100 – 200) = 100 J. The negative sign indicates that work is done by the system.
