WebMar 27, 2024 · Vector projection is useful in physics applications involving force and work. Solution When the box is pulled by vector v some of the force is wasted pulling up against gravity. In real life this may be useful because of friction, but for now this energy is inefficiently wasted in the horizontal movement of the box. Example 2 WebJan 27, 2024 · The projection of a onto b points in the same direction as b. So all we need to do is take the vector b and scale it by the scalar projection. The easiest way to do this is to first calculate the unit vector and then simply multiply it by the length of the projection of a onto b. proj_ba = \frac {b} { b } \frac {a \cdot b} { b } = \frac {a ...
