what is friction? give examples of it? types of friction with examples?
Answers
Answer:
friction is the force between two surface
Explanation:
there are two types of friction sliding friction and rolling friction ,=when an object start rolling over another is called rolling friction . sliding friction= when an object tries to move with the help of sliding is called sliding friction.
Answer:
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.
Everyday Examples of Friction:-
Rubbing both hands together to create heat.
A sled sliding across snow or ice.
Skis sliding against snow.
A person sliding down a slide is an example of sliding friction.
A coaster sliding against a table.
A washing machine pushed along a floor.
An iron being pushed across material.
There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
Static Friction Examples:-
Papers on a tabletop.
A towel hanging on a rack.
A bookmark in a book.
A car parked on a hill.
Examples of Sliding Friction:-
A child sliding down through a slide in a park. A coaster sliding against a table. A washing machine pushed along with the floor. Two cards in a deck sliding against each other.
Some examples of items that have rolling friction are:-
Truck tires.
Ball bearings.
Bike wheels.
Soccer ball, basketball, or baseball.
Car tires.
Skateboard tires.
Railroad steel wheels.
Bowling ball.
Fluid Friction Examples:-
A vase sitting on a table. Riding a bike. A seagull soaring through the air. Air resistance is an example of fluid friction caused by the particles that make up air.
