Answer #1

This is the dot product relation from linear algebra. This signifies the scaler property of work.The work done on an object is found by multiplying force and distance, but there is a catch. The force and distance must be parallel to each other. Only the component of the force in the same direction as the distance traveled does any work.Hence, if a force applied is perpendicular to the distance traveled, no work is done. The equation becomes force times distance times the cosine of the angle between them.

Coriolis' alternative method for finding work can be used to estimate the relative stopping distance for a car given the car's speed. For this application of Coriolis' alternative method, the force of friction is in the opposite direction of the motion of the car on which that frictional force is acting, and the "work required to stop the car" (sometimes called "the work done by friction") is equivalent to the amount of mechanical energy converted to thermal energy by the...
