GEOLOGY

Detailed explanation-1: -Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.

Detailed explanation-2: -FRICTION: is a force that works against motion; the action of one surface or object rubbing against another surface or object. Friction stops or slows down moving objects. Friction can help moving objects change direction.

Detailed explanation-3: -Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car. Friction also prevents an object from starting to move, such as a shoe placed on a ramp.

Detailed explanation-4: -friction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

Detailed explanation-5: -Critical teaching ideas. A useful model for explaining friction is the idea that all surfaces have tiny bumps. When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface which is in the opposite direction to its motion.
