If you do your measurements on the CGS (centimeters, grams, seconds) system, force is expressed in dynes and work in ergs. You must convert these to newtons and joules to get the result in watts. Here are the conversion factors: 1 dyne = 10−5newtons 1 erg = 10−7joules You can...
In this project, you're going to be building a model trebuchet. Although you won't be able to storm cities, this project will teach you about...
Joules is a measure of energy. In order to convert from watts to joules, you need to specify a length of time.[12] The longer a current flows, the more energy it uses. 2 Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you...
