This document discusses how to calculate work by multiplying force times distance. It provides the formula that work (W) equals force (F) times distance (D). It then works through an example of calculating the work done by lifting a 200 Newton object 0.5 meters, which equals 100 Joules. The document concludes by listing some sample problems for calculating work using various forces and distances.

2. Calculating Work
•Work = force (N) x distance (m)
• W = F x D
• The unit for work is a Joule (J).
• If you lifted an object weighing 1N through a distance
of 1m, you did 1 Joule of work:
W = FD = 1N x 1m = 1 J

3. Calculating Work
•If you lifted an object weighing 200 N
through a distance of 0.5m, how much
work would you do?

4. Calculating Work
•If you lifted an object weighing 200 N through
a distance of 0.5m, how much work would
you do?
Work = force x distance = 200 N x 0.5m = 100 J.

5. Problems
1. Calculate the work done by a 47 N force pushing a pencil 0.26 m.
3. Calculate the work done by a 2.4 N force pushing a 400. g sandwich across a
table 0.75 m wide.
4. How much work is it to lift a 200 Newton sack of potatoes vertically 6.5 m?
5. If a small motor does 520. J of work to move a toy car 260. m, what force does it
exert?
