Question

necessities of friction?​

Answer 1

Explanation:

Friction is important also for these reasons: (1) It causes air in the PBL to converge toward low pressure and diverge from high pressure (friction causes PBL air to flow toward low pressure) (2) friction is a little stronger over land surfaces than over water surfaces since land surfaces have a more rough and vertical ...

Answer 2

Friction:-

The force that acts upon two surfaces that are in contact and opposes the motion of one object over the other is called friction.

Necessities of Friction:-

• Spikes are always present in shoes of players so as to increase friction, by these they maintain a better grip on ground and it prevents skidding.
• We are able to write anything because of friction that is present between the tip of our pen or pencil.
• The friction between tyres of vehicles and the ground help in moving on the ground. Usually grooves are present on tyres, that provide better grip.
• Friction is very helpful in walking, its present between our feet and ground.
• Matchstick is lit only because of friction, that is present between match box and matchstick
