Can work be measured in joules
WebSo, the reason you can't use Joules for torque is because there is no consistent way of converting Newton-meters to Joules and vice versa. There are 2 types of units viz., the … WebAnswer (1 of 9): Well, James Prescott Joule worked hard for it. () But, all seriousness aside, SI units named after people are generally named after people who worked hard on the subject area in which a specific quantity is to be measured in the so-named units. It should then not surprise...

Heat is measured in joules because James Prescott Joule experimentally showed that mechanical energy is converted to heat in 1843. For more details study thermodynamics and statistical mechanics. pennsbury high school elective coursesWebA physicist defines work (W) as the force (F) multiplied by the distance (d) over which it is exerted. This is expressed as W = F x d. Work is measured in units called joules (pronounced "jools"). When you hold your arms over your head, you aren't moving anything. But mechanical work involves both force and distance, and there isn't any distance. pennsbury high school football 2021
