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).

Friction is the force that opposes motion between any surfaces that are in contact. ... Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.

Advantages of Friction: Friction is responsible for many types of motion. It helps us walk on the ground. Brakes in a car make use of friction to stop the car. Asteroids are burnt in the atmosphere before reaching Earth due to friction.

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.

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.

Helpful frictional forces For example: friction between our shoes and the floor stop us from slipping. friction between tyres and the road stop cars from skidding. friction between the brakes and wheel help bikes and cars to slow down.

4 Laws of kinetic or dynamic friction. The force of friction always acts in a direction, opposite to that in which the body is moving. The magnitude of the kinetic friction bears a constant ratio to the normal reaction between the two surfaces.

The examples I can think of, from everyday experience, where friction would be unwanted are when you're trying to move something heavy. Sliding a heavy object across the floor will be made difficult by friction. My car going through the air causes friction, and that reduces my fuel efficiency.

The actual mechanical advantage of a machine reflects the increase or decrease in force achieved by the machine. It takes into account the force needed to overcome friction. The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction.

Kinetic friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. Static friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces.
