What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to momentum. 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 momentum, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Subtracting the speeds in a rebound instead of adding them.
- Forgetting that momentum is a vector and ignoring signs.
- Saying kinetic energy is conserved in a collision the question has told you is noisy or sticky.
- Writing the changes in momentum of two colliding objects as equal without the opposite sign.
- Assuming the incoming object always stops after a collision.
- Quoting momentum in newtons, or impulse in kg m/s² .
- Thinking a crumple zone reduces the change in momentum rather than the force.
Revise it first
