What is the meaning of resistive force?
Answer:
The resistive force, also known as the balancing force or opposing force, is a force that acts in the opposite direction and equal magnitude to counteract the effects of an applied force or force system on a body. It is responsible for maintaining the equilibrium or balance of the body under the influence of external forces.
When multiple forces act on a body, the resultant force (also called the net force) is the vector sum of all the forces. The resistive force acts in such a way that it cancels out the effect of the resultant force, ensuring that the body remains in a state of rest or moves with constant velocity.
The resistive force can occur in various forms depending on the specific situation. For example, in the case of an object moving through a fluid medium like air or water, the resistive force is called drag or fluid resistance. It opposes the motion of the object by exerting a force in the opposite direction.
In mechanics, the resistive force can also be caused by factors like friction, air resistance, or the tension in a string or rope. These forces work to counteract the applied force and prevent the body from accelerating or changing its state of motion.
Understanding and calculating the resistive force is essential in physics and engineering to analyze the behavior of objects and systems subjected to different forces. It helps in determining the equilibrium conditions, predicting the motion of objects, and designing structures that can withstand external forces effectively.
