Measuring Work
Measurement is finding a number that shows the size or amount of something.
Work is the amount of energy necessary to move an object. A person can push against a brick wall until they sweat. But unless they moved the wall — even a tiny bit — they did no work. But at the same time, if you scoot the computer mouse even a part of an inch, you have done work. Work in the scientific sense. Don't try to convince your parents or your teachers that you have done a lot of work by playing video games.


Work can be measured. It is measured by the amount of distance that a force moves an object. Sir Isaac Newton was a very famous scientist who had a wonderful understanding of the relationship between force and motion. For this reason, the measurement is known as a Newton. It is abbreviated with a capital N. The term joule is often used to measure work as Newtons per meter. If it takes 1 Newton to move any object 1 meter, then that is equivalent to a joule
There are special tools for measuring the force necessary to move an object. These are known as force meters. They use a spring and a hook to determine how much pull is required to slide an object up an inclined plane. Really very simple to use.
A number that shows the size or amount of something.
