# The Definition of Parallel Forces

When considering the forces that act on an object, it’s important to understand the role of parallel and perpendicular forces. Although each force has a similar effect and each has a different direction, they all have a different effect. One example of a force that acts upon an object is the gravity force. The perpendicular component of gravity balances the parallel force, while the parallel force causes acceleration. These forces together are called the net force.

Another definition of parallel forces is that they act in the same plane, but their lines of action never intersect. In addition, they can act in opposite directions. A spinning top, for example, may move at a constant velocity but will not change its position unless it is pushed by an external force.

When a force acts on two objects at once, it is considered to be in equilibrium. This happens because the forces act on two different bodies. The action force is directed toward one object, while the reaction force acts on the other. It is possible for two objects to be in equilibrium with each other, but this is not desirable.

The difference between concurrent and parallel forces is that their lines of action are parallel, but they never intersect. The sum of the force vectors’ magnitudes is the resultant. A parallel force vector is a general force system that works on an object’s A-plane. The vectors of parallel force are what determine the object’s weight.

Although the forces of reaction and action act on opposing bodies, their effects cancel each other. This is important as it prevents friction from changing the body’s speed. Friction, on one hand, is resistance to motion but is not a fundamental force. Work, on the other hand is the use force to move an object. In order for work to be effective, it needs to be applied in the same direction that the object is moving.
