Hey,
I need to learn uhm 17 forumlas.
Really I need to know them for tomorow.
And I just can´t remember them all.
Does anyone have a little rhyme or so I can use to remember them all?
They are the basic IGCSE forumlae, e.g
1. Distance "divided" by speed x time
2. Change In speed "Divided" by accelaration x time
3. Force "Divided" by mass x accelaration.
etc.
Anyone know a good way of remembering them?
Thank you!

Usually the best way to learn these is repetition or by using the formulas a lot.

You know actually ive repeated these formulas like 5000 times and still I go do something else then come back and I can hardly get them right.
And lol using them?
To time consuming.
But thanks!

For the ones like distance, velocity and acceleration, just remember them in that order

velocity = change in displacement/time, acceleration = change in velocity/time.

Or you could work them out using units. Example, speed has units m/s and time has units of s.

If you multiply them, your units become (m/s)(s)= m, which is a distance.

Yeah I suppose.
That would work.
Thank you!
