Basic Formula: 
W = F x d 
** This should make sense, when we want to know how much
work went into moving something, we need to know how much force it took
and how far, right? 
W = work 
d =distance 
F = force 



Units: 
Work will always be a
distance unit times a force unit. It is usually a newton*meter (Nm) 
also known as a Joule (J) 

Distance unit: m
(meters) 

Force units: usually in N (newtons)

These problems are not really
very hard to solve as long as you match the given numbers (usually using
their units) with the formula above. You can also use the triangle
method. The triangle is an easy way to figure out how to manipulate
the formula. In order to use it, look at the triangle. Put
your finger over the variable or letter you need to solve for. For
example, if you are looking for work, you will cover up the letter
W. Now you do the mathematical function it shows. If the
letters are beside each other, you multiply. If one is on top of the
other, you divide. If you would like to check out some sample

The triangle: 
You
can see that if you were trying to solve for Force need to do some work,
then the W(J) would be over the d, so you would divide the work done by the
distance you did it in. Similarly, if you wanted to solve
for the distance an object would move, then the work(J) would be divided by the
force (N) you applied since the work(J) is
on the top. If you
wanted to solve for the work(J) it took to complete the task, then the
Force(N) would be located beside the distance,
so you would multiply them together.
