Friction provides traction for walking and driving vehicles, allowing us to move safely on surfaces. It also helps in holding objects together, such as screws or nails, preventing them from sliding apart. Additionally, friction helps in converting kinetic energy into thermal energy, such as in brakes slowing down a moving vehicle.
Friction provides grip for tires on a road surface, allowing vehicles to move forward. It also helps in writing by allowing the pencil to grip the paper. Additionally, friction between our shoes and the ground prevents us from slipping.
Types of friction include static friction (sliding), kinetic friction (rolling), and fluid friction (fluid). Examples of sliding friction include pushing a heavy box across the floor, rolling friction is experienced when a ball rolls on the ground, and fluid friction occurs when swimming in water.
Advantages of friction: It allows us to walk without slipping, helps stop moving objects, and provides grip for vehicles on roads. Disadvantages of friction: It causes wear and tear on surfaces, reduces efficiency in machines, and can generate heat leading to energy loss.
Examples of using friction at home include opening jars with a grip pad, scrubbing dishes with a sponge, and using sandpaper to smooth surfaces.
Three examples of low friction are ice skating on smooth ice, a sled sliding down a snowy hill, and a ball bearing rolling along a hard surface.

Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.
The fact that you can walk without sliding is an example of friction.
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.

1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
