WebW net = W grav = − m g ( y f − y i), where y is positive up. The work-energy theorem says that this equals the change in kinetic energy: − m g ( y f − y i) = 1 2 m ( v f 2 − v i 2). Using a right triangle, we can see that ( y f − y i) = ( s f − s … Webmoving things have energy we call this the kinetic energy but the question is how much kinetic energy does a moving thing have for example if we knew the mass of this ball let's say it was 2 kilogram and let's say it was …
