Question

What is Friction?
And what are its uses??​

Answer 1

Answer:

Friction is a resistance force that slows down or prevents motion, it is necessary for many applications where you might want to hold items or do things and prevent slipping or sliding.

Friction is used in car brakes, when we walk or climb a hill, making a fire, skiing down a hill, and more.

Answer 2

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

Explanation:

• Following are the ten examples of friction in daily life: Walking –We can walk only if we apply frictional force. Friction is what holds your shoe to the ground. The friction present on the ice is very little, this is the reason why it is hard to walk on the slippery surface of the ice.
• Friction between the surface of the road and tyres of our vehicles allow the vehicles to move without slipping. Friction produces heat causing wastage of energy in machines. Friction causes wear and tear of moving parts of machinery, soles of shoes, etc.
