## The principle of work and energy cannot be used, in general, to determine forces directed normal to the path, since these forces do no work Note that the principle of work and energy (T 1 + U 1-2 = T 2) is not a vector equation! Each term results in a scalar value Both kinetic energy and work have the same units, that of energy!

### Revisiting the work energy theorem The work energy theorem says the total work is equal to the change in KE W net KE 2 KE 1 On the other hand, we have seen that the work due to gravity ONLY DEPENDS ON THE INITIAL AND FINAL POINT OF THEIR PATH, NOT ON THE ACTUAL PATH. These type of forces (of which gravity is one) are called conservative forces.
