Calculating Work (W=Fxd) Worksheets and Key
If you have been teaching a Simple Machines or Energy Unit, then you need to check out this three page lesson to teach calculating work. It is in three sections.
Section 1: Picture Questions
Section 2: Word Problems/with Challenge Questions
Section 3: Charting/Graphing Problems
All problems are worked out and the key is included.
These worksheets include the renown Triangle Method, which has been a proven problem solver for students who struggle in math.
The triangle method can help you rearrange the formula:
#1 Cover up one of the three letters that you want to solve for.
#2 If the other two are side by side you multiply them to get the third.
#3 If one letter is above the other, divide the letter above by the letter below.
In the work problems you have below, use the wording of the question to decide which formula to use.
If the problem asks:
How much work is done? or What is the work? Use the formula W = Fd.
What force was needed? Then use the formula F = W / d.
What distance was moved? Then use the formula d = W / F.
Show your work on all problems as in the following examples. Use the units to identify the numbers given in the problem. Write down each number and unit and what letter in the formulas it is equal to. Decide what the question is asking for and write the correct formula. Then substitute the right numbers for the parts of the formula and multiply or divide the two numbers to get the answer. **Never forget to put the correct unit after the answer.
