Equilibrant forces are those that act on a body at rest and counteract the force pushing or pulling the body in the opposite direction. Equilibrant forces establish equilibrium for an object and make the object motionless. Equilibrant forces act on virtually every object in the world that is not moving.Know More
The force of gravity is pulling down a cup sitting on a desk. The only way the cup can keep from crashing into the ground is if something pushes up on it at least as hard as gravity is pulling it down. The table or counter top holding up the cup supplies the equilibrant force, which keeps the cup up. If the table exerted more than equilibrant force on the cup, the cup would rise in the air.
Equilibrant forces can push or pull on an object as long as both forces are imparting the same type of force, but in the opposite direction. Sometimes, equilibrant forces work in concert with each other to offset opposing forces. For example, if three cables suspend a load, each is imparting a force that is equal to one-third of the force of gravity. Likewise, a load suspended by four cables imparts one-fourth of the pull of gravity on each cable.Learn More
The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.Full Answer >
A net force is the remaining force that produces any acceleration of an object when all opposing forces have been canceled out. Opposing forces decrease the effect of acceleration, lowering the net force of acceleration acting on an object.Full Answer >
Friction always opposes motion between two surfaces, although it is not a fundamental force of the universe like gravity. The coefficient of friction is used to describe the ratio of friction between two bodies and the outside force pressing them together.Full Answer >
When a force is applied to an object resting on a surface, a retarding force is that which opposes the force being applied to the object. A retarding force is usually that of friction, which must be overcome when moving an object resting on a surface. If the object is being moved upward along an inclined plane, gravity represents an additional force that must be overcome.Full Answer >
