Mechanics questions and practice

Resolve forces, follow motion and oscillations, and account for energy and momentum.

Simple harmonic motion questions

Calculate periods, signed acceleration, speed and energy; use the small-angle pendulum model.

Resolve forces, balance moments and distinguish force from torque.

Calculate work and power, conserve signed momentum and compare collision energies.

Choose equations and solve constant-acceleration problems with signs, braking and vertical motion.

Calculate stress, strain and Young modulus from wire dimensions and force–extension data.

Process repeated timings, find g from squared-time graphs and evaluate timing errors.

Choose SUVAT for straight-line motion, then forces or energy to explain what changes the motion.
