The unit for work, then, is the Newton-meter (F x d). The same unit can also be used for measuring energy. Scientists decided to honor one of the early investigators of the concept of energy. Sir James Prescott Joule (1818-1889) by giving the Newton-meter a nickname, the joule. 1 Newton-meter = 1 joule

joule (J). The joule is named after Prescott Joule. The joule is also the unit of energy. So, work involves a transfer of energy. In this sense, then, energy can be defined as the capacity to do work. The Engineering unit for work is pound∙foot (lb∙ft), where 1 J = 0.7376 lb∙ft) Sign of Work. Work is a . …

Aug 05, 2013 · The unit for kinetic energy is the joule. The equation for kinetic energy is: K stands for kinetic energy, m is the mass of the object, and v is its velocity. How much kinetic energy does a 2.5 kg ball possess if it is thrown with a velocity of 21 m/s? Very simple problem, just use the equation.

Your answer will have Joule as the unit. Calculate the volume of ice melted. (See equation 2 in the introduction.) Calculate the mass of ice melted. (See equation 3 in the introduction.) As in step 8, 1 ml of water has a mass of 1 g. So it’s just the volume changed to grams.
