Resultant Forces with Vectors

In physics, the resultant force is the single force that represents the combined effect of multiple forces acting on an object. Forces are vector quantities, characterized by both magnitude and direction. To find the resultant force, we add the individual force vectors using vector addition.

Example: Two Forces Acting on an Object

Consider an object subjected to two forces:

  • $\vec{F_1} = 5 \,$   N at $0^\circ$ (along the positive $x$-axis).
  • $\vec{F_2} = 3 \,$   N at $60^\circ$ from the positive $x$-axis.

We aim to find the resultant force $\vec{F_R} = \vec{F_1} + \vec{F_2}$.

Step 1: Resolve Forces into Components

Express each force in terms of its $x$- and $y$-components:
