negative times negative equals positive

Angles that are formed by counter clockwise (anti clockwise) rotation, such as the one shown in fig (ii) are said to be positive or to have positive measure. Angles that are formed by a clockwise rotation, like the one in fig(iii) are said to be negative or to have ..

> Let us push a box on a table (a rough horizontal surface). The motion of the box is opposed by the force of friction. The force of friction and the displacement of the object always make an angle 180 o and hence, the work done by the frictional force is always negative. When a positiveh..
