As you already said One Joule is 1 Joule is 1 newton exerted through a distance of one meter. Joules measure how much energy you need to give to the system to move it from point A to point B. And, as you rightly said it is measured by W=F*d. So 490 J is 490 N over 1 metre as 490 ∗ 1 = 490 also it ...
WebBy definition, one watt is equal to one joule of work done per second. So if P P P P represents power in watts, Δ E \Delta E Δ E delta, E is the change in energy (number of joules) and Δ t \Delta t Δ t delta, t is the time taken … WebThe dimension of Planck’s constant is the product of energy multiplied by time, a quantity called action. Planck’s constant is often defined, therefore, as the elementary quantum of action. Its value in metre-kilogram-second units is defined as exactly 6.62607015 × 10 −34 joule second. Britannica Quiz.
