Common mistake
Confusing Resultant Force Definition
Students often define resultant force as the total of all forces acting on an object, rather than as a single force that has the same effect as all the forces.
To fix this, remember that resultant force is not just a sum; it is the net effect of all forces acting on an object, which can be a single force in a specific direction.
