Work and Kinetic Energy Newton s second law defines the Workenergy Theorem 0 Work is force over distance o If there is no distance there is no work done despite the force applied on the object o If the velocity is perpendicular to the force there is no work done because cos 90 is 0 Relationships between Work and other variables1 o If work is in the same direction of velocity then W gt 0 and the object speeds up o If work is in the opposite direction of velocity then W lt 0 and the object slows down o If force is perpendicular to velocity then W 0 and the object continues at its original speed What is Work 0 Work is the transfer of energy 0 Work is equal to the change in kinetic energy 0 Work measure the energy that a force puts into or takes away from an object as it moves What is Energy 0 Energy is the ability to do work 0 Different energies include kinetic energy potential energy gravitational elastic electromagnetics chemical radiant thermal etc 1 These relationships are based upon an object on a frictionless surface er am Kin c 611 dafmdmn dbl L di l Hmcnai7 W V Cmsmf 9 e7 V f m Fa f w Pd 4 w lFJazm ug1Fo 33 Meow quot0361605 9047 M O ZW de Wort 14mm 93 Wimp u Z w Zaab P b i l hu f dd J2 I39Mp7 WLZ Fnddg w 145 inn139quot W int quot K k
