· 4.10 understand that work done is equal to energy transferred PFY p.112 [cid:image001.png@01CC6D66.70900440]
a) the work done (measured in joules) is equal to the force (in newtons) multipulied by the distance moved (in metres)
b) 1 joule is the work done when a force of one newton moves through a distance of one metre ( in the direction of the force). work dorn + energy transferred. [cid:image002.png@01CC6D66.70900440]
word done = 5 x 2 = 10 J [cid:image003.png@01CC6D66.70900440]
work done = 500 N x 40m = 20,000 J
