Hello Arthur, the formulae will be remembered well only when we make continuous attempts to solve problems. Now we the answerers recall many formulae so quickly. It is mainly because we always keep in touch by solving many many problems. As our friend has pointed out better hang a board with all the important formulae written where you usually brush you teeth and comb your hair. Write down the formulae often in one day at different times.

I've found it helps to just do a ton of problems. Everytime I do a problem I always write the formula, even if I think I already know it. Eventually you see the signs. It's difficult to just tell you what those are because they're often worded differently.

As cliche as it sounds, practice makes perfect.

Personally I've found that knowing where the formula comes from works best. If you understand the concept, it's easier to recognize if you're missing a variable or constant. Pure memorization can actually be useless sometimes because there are circumstances that have to be met.

:o is correct.

Memorize the way the basic units, mass, time, distance, charge, etc. combine to make up the more complicated ones. Most of them are pretty easy if you understand where those units come from: velocity is rate of change in distance, which is distance over time. Acceleration is rate of change of velocity, which is velocity over time, which is distance over time squared.

If you know some calculus, you can keep in mind the derivation of the formulas, they are often interrelated by derivatives. Velocity is the derivative of distance and acceleration is the derivative of velocity. That helps with factors of 2 and 1/2, for example, which can't be easily determined by the units. Otherwise, you'll just have to memorize the extra factors.

Here's an example:

Units of force are units of mass x distance / (time)^2

distance/time^2 is acceleration, so F=ma

mass x distance/time = momentum, so F = P/t

Energy/Work = mass x distance^2 / (time)^2

W = Fd

KE=1/2mv^2

PE=-mgh

etc.

Work as many problems as you can with them. If you are paying attention and considering the physical problem in your mind, after a couple of problems you will know all the formulas. It is also important to pay attention to their derivation: if a detail slips your mind a quick recall of even parts of it will allow you to write the formulas in full.

Memorizing is not good for physics, personally I remember the units. Eg) I Know E = N/C so I just find what units would make N/C like (F)/ (Ixt) would be N / ( C/s x s) = N/C
