What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to mass and weight. 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 mass and weight, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Giving a mass in newtons or a weight in kilograms.
- Saying an object's mass decreases in space, or on the Moon.
- Using Earth's g when the question supplies a different value.
- Dividing by six instead of multiplying, when asked what mass gives the same weight under weaker gravity.
- Saying a beam balance would give a different reading on the Moon.
- Forgetting that extra mass makes stopping harder as well as starting.
- Treating g as if it had only one meaning; it is both a field strength in N/kg and an acceleration in m/s².
Revise it first
