IMPULSE: F = ∆(mv)/∆t ⇒ F ∆t = ∆ (mv)
... object is equal to the change of its kinetic energy. W = F d = ∆(½ m v2) By Newton’s third law the force acting on the object is equal and opposite to the force exerted by the object on the external agent! Therefore, the work done by that force – by the object is equal to the work done on it with a ...

... • When the volume is greater than the initial volume, as in expansion, the logarithm in above equation is positive and hence w<0. In this case the system has done work on the surroundings and there is a corresponding reduction in its internal energy. • From the equation also show that more work is d ...
