Final answer:
The equivalent resultant force is the sum of all the forces acting on an object. It is calculated by adding the magnitudes of the forces in the appropriate direction. If the forces are represented by vectors, the resultant force is the vector sum of all the forces.
Step-by-step explanation:
The equivalent resultant force is the sum of all the forces acting on an object. It is calculated by adding the magnitudes of the forces in the appropriate direction. If the forces are represented by vectors, the resultant force is the vector sum of all the forces.
For example, if there are two forces acting on an object - one of magnitude 10 N in the positive x-direction and another of magnitude 5 N in the negative y-direction, the resultant force can be calculated as:
Resultant force = 10 N - 5 N = 5 N
The resultant force is positive and acts in the positive x-direction.
