What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to forces. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on forces, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Putting a single force into F = ma instead of the resultant.
- Using the stretched length instead of the extension in Hooke's law.
- Taking the spring constant from a reading past the limit of proportionality.
- Accepting a case as equilibrium when the forces cancel but form a couple.
- Using a distance that is not perpendicular to the force when finding a moment.
- Saying the centre of gravity is at the point of suspension, or halfway down the vertical.
- Drawing the force on an object in circular motion outwards or along the tangent.
- Saying an object at constant speed has no forces acting on it.
Revise it first
