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.
The retarding force represented by friction can take on various forms. Dry friction refers to the retarding force existing between two solid surfaces in contact with each other. Skin friction, also known as drag, represents the force offering resistance to a fluid moving across the surface area of a body.Learn More
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 >
Centripetal force refers to the force that makes objects move in circular paths. Centripetal force makes an object or body follow a curved path; the direction of the body moves towards the center or fixed point of the circular path.Full Answer >
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.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 >
