Question

Explain how Friction is advantageous to us?

Answer 1

Hint: Friction is the force exerted by two surfaces sliding (or attempting to slide) across one another. When you try to push a book across the floor, for example, friction makes it difficult. Friction always acts in the opposite direction from where the thing is going or attempting to move.

Complete answer:
Walking is tough without friction. Friction pulls us ahead by providing a force in the reverse direction. You may have observed that walking on slick terrain or sand dunes is really tough. Friction allows us to turn because it gives us control. Manure may be easily applied due to the resistive force.

Consider roller skates; turning is difficult due to the minimal friction provided by the wheels.A car's brakes operate on the concept of friction. As a result, an item will not come to rest on its own if there is no friction. Newton's first law asserts that unless acted upon by an external force, an object in motion will continue in a straight line.

Friction between parts in a machine aids in energy transfer in mechanical engineering. The pieces will slip if there is no friction, and there will be no firm contact to transfer energy.The rubbing of two bodies creates heat owing to friction. This method of generating fire with dried tree branches and stones has been used for centuries. Frictional force may also be used to ignite a matchstick. The friction between our hands and the item we're holding aids in gripping the thing. Consider how easily the thing would slip from your hands if there was no friction.

Note:Friction makes it easier for us to walk on the ground. Friction allows us to write on paper or a board. Friction aids in halting a vehicle when the brakes are applied. When we rub our hands together, it helps to generate heat. Asteroids burn in the atmosphere before hitting the earth, saving lives on the planet.
