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.
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
Some examples of luminous objects are a burning candle, a light bulb, the sun and other stars, fluorescent materials and tube lights, among other things. Any object is considered luminous if it emits its own light, either through stored energy or energy supplied to the object, which contrasts with non-luminous objects such as the moon, wood, plastics and metals; these objects merely reflect light instead of providing their own.Full Answer >
Drift velocity describes the overall velocity of a particle that moves continually and changes its velocities and directions randomly. This velocity is best understood when imagining the free electron movement in a conductor.Full Answer >
Nuclear fission was discovered in 1938 by two German scientists, Otto Hahn and Fritz Strassmann. In 1939, it was explained theoretically by Lise Meitner and Otto Robert Frisch.Full Answer >
Matter made up of a single kind of atom is referred to as an element. Atoms are defined as the smallest particles of a given element that still express the element's chemical signatures.Full Answer >
