Friction can be useful. For example: friction between our shoes and the floor stop us from slipping. friction between tyres and the road stop cars from skidding.

Static friction is the friction experienced by a body at rest. Limiting friction is an amount of force which is required to be applied to just overcome the friction, for forces larger than limiting friction the body is set into motion.

I know that friction is the resistance to motion that occurs between objects. So friction is a force that work opposite the direction you rub an object against another object. ... If the friction is negative then the direction will be the same as you rub an object against another object.

Ideally, the coefficient of kinetic friction only depends on the nature of the surfaces. It does not depend on any other factors, including the relative speed of the surfaces and the surface area of contact.

Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced.

Friction is a contact force when two surfaces interact. The second equation is the kinetic frictional force that is used when two surfaces are sliding against each other.

By making the surface rough friction can be increased. Examples of increasing friction-the tyres of a motor car and bicycles are made rough to increase the friction . when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction.

Hey friction is not an energy. Basically it is the medium to convert kinetic energy into thermal energy which get stores in a body.. ... Friction is a phenomenon that opposes relative motion between two surfaces in contact. Frictional force is a type of force.

Friction is the force that resists the relative motion or tendency when two substances are in contact. ... Static friction is greater than kinetic friction. To find static friction, it equals the product of normal force (Fn) and static friction coefficient (Fs).

Static friction is greater than kinetic friction because there are more forces at work keeping an object stationary than there are forces working to resist an object once it is in motion.

Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.

Examples. Water, air, alcohol, glycerol, and thin motor oil are all examples of Newtonian fluids over the range of shear stresses and shear rates encountered in everyday life.

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object. The characteristic of a high friction surface tends to be coarseness.

Some examples of materials wearing out due to friction include automobile ties, the soles of your shoes, a pencil eraser, as well as machinery. With friction caused by molecular adhesion, wear is caused when molecules get torn loose from a material.
