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.Continue Reading
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 about Physics
An object's acceleration is constant and downward due to the force of gravity In projectile motion, but the object's velocity reverses direction during the object's motion. This is because of the inertia described in Newton's first law of motion and because acceleration and velocity are two different physical quantities. Velocity is the speed and direction of an object, while acceleration is the rate that the velocity changes.Full Answer >
Parallel force systems are those in which forces act in the same direction. The opposite of a parallel force system is a perpendicular force system, which is a system that has forces acting at right angles to each other.Full Answer >
Unbalanced forces that have a net force in a certain direction are what lead to changes in motion. When multiple forces act on a body, the resultant force, calculated as the vectorial sum of the individual forces, determines whether the body moves or not.Full Answer >
The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.Full Answer >
