Reference Frames & Relative Motion FRQ Set
Write a complete response before opening the reasoning guide. The four prompts deliberately use different response modes.
Train T moves +24 m/s relative to ground G. Passenger P walks −3 m/s relative to T. Determine v_P/G and v_G/P, showing a consistent subscript equation.
Reasoning and scoring guide
v_P/G = v_P/T + v_T/G = −3 + 24 = +21 m/s. Reversing the pair gives v_G/P = −21 m/s.
Draw or describe velocity arrows for a car moving +20 m/s and a truck moving +14 m/s in the ground frame. Then represent the car in the truck frame and the truck in the car frame.
Reasoning and scoring guide
v_car/truck = +6 m/s and v_truck/car = −6 m/s. The two relative velocities are equal in magnitude and opposite in direction.
Design a one-dimensional classroom investigation using two battery carts to measure one cart’s velocity relative to the other. State what ground-frame measurements are needed and how to combine them.
Reasoning and scoring guide
Measure each cart’s signed ground-frame velocity over the same interval, then calculate v_A/B = v_A/G − v_B/G. Repeat for same- and opposite-direction motion.
Two inertial observers move at constant velocity relative to each other. They disagree about an object’s velocity but agree about its acceleration. Explain why this is consistent with Topic 1.4.
Reasoning and scoring guide
Changing inertial frames adds/subtracts a constant frame velocity, shifting measured velocity. The derivative/change rate of that constant shift is zero, so acceleration remains the same.
