Answer:

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. ... 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.

example :-

- Driving of a a vehicle on a surface.

- Applying brakes to stop a moving vehicle

Explanation:

hope it's help you...

 \huge \pink{definition}

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact

 \huge \purple{example}

  • Driving of a a vehicle on a surface.
  • Applying brakes to stop a moving vehicle.
  • Skating.
  • Walking on the road.
  • Writing on notebook/ blackboard.
  • Flying of aeroplanes.
  • Drilling a nail into wall.
  • Sliding on a garden slide.

 \huge \blue{formula}

This constant ratio is called the coefficient of friction and is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/L. Because both friction and load are measured in units of force (such as pounds or newtons), the coefficient of friction is dimensionless.
