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: A force that opposes two objects sliding against each other. Friction acts in a direction along the flat surface of an object. normal force: The force exerted by the ground or other object that prevents other objects from going through it.

Friction happens when electrons are "wiped' from 1 object onto another. For ex. rubbing a plastic ruler with a cloth. Induction is when charges in an uncharged metal object change "without direct contact" with a charged object.

There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.

Examples of frictional unemployment include: Quitting, a voluntary form of frictional unemployment. Termination, an involuntary form of frictional unemployment. Seasonal employment, becoming unemployed because the work is done for the season.

In some cases, friction is desirable while in other cases, friction reduces the effectiveness of machines. Without friction, you would not be able to walk, the wheels on a vehicle would have no grip on a road surfacing and the vehicle would not be able to move forward.

Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of conservative forces are: force in elastic spring, electrostatic force between two electric charges, and magnetic force between two magnetic poles.

['Friction enables us to walk freely.', 'It helps to support ladder against wall.', 'It becomes possible to transfer one form of energy to another.', 'Objects can be piled up without slipping.', 'Breaks of vehicles work due to friction.', 'It always resists the motion, so extra energy is required to overcome it.']

Friction is a good example of a non-conservative force because if removes energy from the system so the amount of mechanical energy is not conserved.

No. It can not exist. Static or sliding frictions are always there acting on the object. Frictional force and the applied force are always in opposite direction.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

Advantages. The force of friction acts in the opposite direction that the object is moving, so friction slows down the motion of moving objects. Friction also produces unnecessary heat. For example, car engines become hotter because of friction.

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.
