Question

What happens when two forces act in the same direction?

Answer 1

1. When two forces acting on a body are in the same direction, they are added together to form a stronger force.
2. When two forces act in the opposite direction the resultant force is the subtraction of the larger force from the smaller force
3. When two forces acting on a body are in the same direction the magnitude of the forces is added together.
4. For example, consider two forces of magnitude $F_A,F_B$ acting in same direction, the resultant force is the sum of two forces,

$F_R=F_A+F_B$

Where $F_R$ is the resultant force
