Question

Given below is a paragraph about frictional forces written by Rohit for his class test. Read it and correct the errors by changing words and sentences.

Friction retards motion as it acts in the direction opposite to motion. We can wall easily on a very smooth floor as it is easier to overcome less friction. Rougher the surface in contact, the Lesser is the friction. A lubricant helps increase friction between moving parts.Fish and birds have streamlined bodies so that the friction is more and they should not slip off while moving.​

Answer 1

Answer:

The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.
