Question

enlist four advantages of friction

Answer 1

ADVANTAGES OF FRICTION IN WEATHER

Meteorologists found that friction decreased surface wind speeds, making them less volatile. Friction also encourages surface air masses to merge and rise, which aids the rain cycle. Rough terrain, trees and buildings create the friction that acts on wind speeds.

ADVANTAGES OF FRICTION FOR ANIMALS

Friction between animal's feet and the ground makes running and walking easier. In fact, without friction, animals would have difficulty standing. It's like the comic scenario of someone slipping on a banana peel: If there's no friction, people and animals couldn't walk; they couldn't plant their feet firmly on the ground. There would be no friction (i.e. traction) to keep their feet from slipping and sliding all over the place.

ADVANTAGES OF FRICTION IN EVERYDAY LIFE

In everyday life, friction between the road and a car's tires help the driver control the vehicle's speed; by applying the brakes, you slow the car to a stop. Friction also makes writing on paper possible. When using a pencil, the paper's friction causes the pencil lead to rub off. When using a ballpoint pen, friction triggers the ball to roll, thereby releasing the pen's ink.

ADVANTAGES OF FRICTION IN SPACE SCIENCES

While in space, meteors and comets have no force to slow them down. As they hit the Earth's atmosphere, however, not only does the atmosphere's friction slow them down, it tends to break them apart into smaller pieces, thereby lessening their impact on the Earth's surface.

Answer 2

we can write with the help of friction
we can hold the things with the help of friction
we can walk on road with the help of friction
we may skid if there is no friction
