This page contains more equation memorization examples. All
use association. The memorization home page is here.
Remember:
First Example - Circumference of a circle
Let’s start with quite a simple example: The circumference of a
circle is 2 π r.
In my story I can see that brave Sir Cumference is the equal of
a hungry pirate looking at two pies (2 π) and making a pirate
sound: aghhh (r). Here’s what I see:
Sir Cumference is the equal of two pi Arghhh!
The images and story are silly, but taken together we have
something that’s strong, bold and unusual, and that’s why it
works. When thinking of associations it often helps to have fun.
For practise, try looking around the room and linking
(associating) two or three things in silly, funny or unusual ways.

Second Example - Force, mass and acceleration
The stories don’t always have to be silly or amusing. Some of
the best, as far as memory is concerned, can be a little scary or
uncomfortable.
The equation for force, mass and acceleration is F = ma. In this
case I see an unhappy mother (“ma”) forcing me to do
household chores:
Force equals an (unhappy) ma!
As always, the images and stories work best if they mean
something to you and are strong and bold. You don’t need to tell
anyone what the images and stories are. Many times, the first
image or story will be the best, but if it’s not working try another
one. This becomes very quick and easy with a little practise.
Third Example - power, energy and time
Hmm… It just so happens that there’s a popular and enthusiastic
British pianist called Jules Holland. Ah… I see a way to do this!
In my story Jules has been playing too long. All I have to do now
is picture this and think of suitable associations:
watts = joules over time
This example works very well for me, but maybe it doesn’t work
for you. Can you think of another example that works better for
you? Give it a little thought and see what you can come up with!
An added bonus of my image and story is that it also includes
the units watts and joules. With a little thought and practise it’s
usually possible to include important information, even if it’s
abstract or otherwise difficult to remember.
Summary and a little more advice
Make your images and stories strong, bold and unusual. The
best pictures are almost always the ones in your imagination,
so make use of them!
Practise by looking around the room and linking (associating)
two or three things together. Make it silly, a little bit scary or
about something that’s important to you. If the first idea doesn’t
work, try another.
The best way to remember something is to understand it, but
the techniques discussed here are another tool in the box. It’s
one that can be very useful when preparing for an exam!
The equation for watts is:
Where:
W = power (watts)
J = energy (joules)
t = time (s)
For the third example I will use a picture and story that may not
mean anything to you, but it does to me. This again stresses the
point that the story and images need to come from you and don’t
need to make sense to anyone else.
This time I want to remember the equation shown on the here:
