Try this

Pick the energy story first, then decide whether the question is asking for energy, rate, or efficiency.

Learn to

Choose between work done, kinetic energy, GPE, power, and efficiency equations from the scenario shown.
Compare energy-store changes and explain where useful output and wasted energy go.
Handle short O Level calculations without mixing force with energy or power with energy.

Exam transfer

Energy methods
Calculation + explanation

Governing idea

W = Fs cos θ, Eₖ = ½mv², gravitational energy change = mgΔh, P = E/t, and efficiency = useful output ÷ total input.

Model boundary

Only displayed energy stores and losses are included. Real systems may also transfer energy through sound, deformation, air resistance, and heating elsewhere.

Avoid this trap

Efficiency is a ratio of like quantities and cannot exceed 100%. Keep joules with joules, or watts with watts.

How to explore

Choose the right equation, compare energy changes, and track useful output versus losses in one O Level explorer.

Predict the outcome, change one variable at a time, then interpret the result. Completion records participation only and does not award mastery.
