2Which pair correctly classifies the quantities as scalar and vector?
A.Speed scalar; displacement vector
B.Velocity scalar; mass vector
C.Energy vector; force scalar
D.Distance vector; acceleration scalar
Explanation: Speed has magnitude only (scalar). Displacement has magnitude and direction (vector).
3The prefix micro (μ) multiplies a unit by
A.10⁻³

A.0.28%
B.2.8%
C.3.6%
D.28%
Explanation: Percentage uncertainty = (0.01/0.36)×100% ≈ 2.8%.
5Precise measurements are best described as measurements that are

A.2.0 m/s²
B.4.0 m/s²
C.5.0 m/s²
D.100 m/s²
Explanation: a = (v − u)/t = (20 − 0)/5.0 = 4.0 m/s².

A.7.5 m
B.11.3 m
C.15 m
D.22.5 m
Explanation: At the top v = 0. Using v² = u² + 2as: 0 = 225 + 2(−10)s ⇒ s = 225/20 = 11.25 m, which is 11.3 m to 3 s.f.

A.acceleration
B.displacement
C.force
D.power
Explanation: The area under a v–t graph is displacement (or distance for one-directional motion).

A.0.33 m/s²
B.3.0 m/s²
C.8.0 m/s²
D.12 m/s²
Explanation: From F = ma: a = F/m = 6.0/2.0 = 3.0 m/s².

NSSCAS Physics (8225) Study Tips from Top Performers

1Drill Paper 1-style MCQs under timed conditions (about 1.5–2 minutes per item for the 1 h 15 min paper), then review every wrong option with a formula check.
2For Paper 2, practise clear multi-step working with SI units — many marks are method and unit marks, not just the final number.
3Memorise core AS formulae: v = u + at, s = ut + ½at², p = mv, FΔt = Δp, W = Fs, Ek = ½mv², ΔEp = mgΔh, P = Fv, F = kx, stress/strain/E, v = fλ, Doppler fo = fv/(v ± vs), λ = ax/D, d sin θ = nλ, E = F/Q, E = V/d, I = nAvq, V = IR, ρ = RA/l, V = E − Ir, potential divider Vout = Vin R2/(R1+R2).
4Expose yourself to real practical procedures (timing oscillations, Young modulus wire, Ohm’s law circuits, interference, graphs of best fit) because Paper 3 tests laboratory skills under timed conditions.
5For waves, practise distinguishing progressive vs stationary waves, and solve double-slit and grating calculations with consistent units for d and θ.
6For nuclear physics, practise balanced decay equations and quark composition of protons and neutrons — examiners’ reports often flag notation and conservation errors.
