Homework Help: Easy way to remember formulae?

  1. May 25, 2010 #1
    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!
