The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. The CAPE Physics Unit 1 case studies are 4 cases and about 1,933 words.
1Block on a Rough Incline: Does the System Move at All?
A 4.0 kg wooden block on a rough plane inclined at 25° to the horizontal is joined by a light string, passing over a small pulley at the top of the plane, to a 2.5 kg mass hanging freely. The coefficients of friction between block and plane are μs = 0.45 and μk = 0.35.

A student uses a plane transmission grating marked '500 lines per mm' and 10 mm wide to try to resolve the sodium doublet at 589.0 nm and 589.6 nm. A collimator produces a parallel beam that falls on the full width of the grating, and the diffracted light is observed through a telescope.

A classroom group studies a horizontal cart attached to a spring on an idealized low-friction track. For this calculation the spring is massless, the track is level, friction is neglected and the restoring law is linear over all displacements used.
