Question :
What are the 15 Examples of Friction in Our Daily Life – Utopper
Solution :
The 15 Examples of Friction Given Below Explain the Concept of Friction in the Detailed Manner :
Friction is the force that stops an object from moving when its surface touches the surface of another object. It can also be thought of as the amount of resistance that the surfaces offer when they move over each other.
We see friction in the things we do every day. Here are ten ways friction shows up in everyday life:
1. Walking: Frictional force is the only way we can walk. Your shoe stays on the ground because of friction. The ice has very little friction, which makes it hard to walk on.
2. Writing : When you write, the tip of the pen rubs against the surface of the paper, which makes a frictional force. When you write with a ballpoint pen, rolling friction happens, but when you write with a pencil, sliding friction happens.
3. Skating: You need a thin layer of water under the blade for the skate to slide. When the skate blade rubs against the surface of the ice, it creates heat. This heat melts some of the ice right below the blade, where the skater moves over the ice. This water acts as a lubricant to make things move more smoothly.
4. Light a Matchstick : When you rub the head of a matchstick against a rough surface, heat is made. This heat changes the red phosphorous in the matchstick into white phosphorous. White phosphorous is very flammable, so the match starts to burn. When there is water around, matchsticks don’t always light. Friction is reduced by water.
5. Driving the car on a flat surface: When you drive a car, the engine puts force on the wheels. The vehicle moves forward because of this force. Friction is the force that keeps the rubber on your tyres from sliding across the road. This friction keeps cars from skidding.
6. Uses of brakes on a vehicle to stop it: Friction braking is the most common way to stop a vehicle. By putting friction on the moving parts of a vehicle, this process turns kinetic energy into thermal energy. The friction force fights against the motion, which makes heat. This change in energy will eventually make the speed stop.
7. Sliding down a garden slide: We know that friction is a force that happens when two things rub against each other. In the event of a slide in the garden, like a slide and a person’s behind rubbing against each other. Without friction, a slide would speed up the rider too quickly, which could cause them to fall and get hurt. The friction slows down the person who is sliding and stops him.
