What is defined as the replacement of one skewed vector by two perpendicular vectors that when acting jointly have the same net effect as the original vector?

Answer: Vector Resolution

Step-by-step explanation:

Vector components can form right triangle, since one acts vertically and the other acts horizontally. Thus, the original vector forms the hypotenuse of the right triangle formed by its components.

The process of breaking a vector down into its components is called vector resolution.
