Question

what is force of friction?​

Answer 1

• When the surface of one item comes in touch with the surface of another, friction is the force that opposes motion.
• Friction reduces a machine's mechanical advantage, or, to put it another way, friction reduces the output to input ratio.
• Limiting friction consumes a fourth of an automobile's energy.
• However, friction in the tyres keeps the automobile on the road, while friction in the clutch allows the car to drive.
• Friction is one of the most important physical phenomena, affecting everything from matches to motors to molecular structures.
• Let's look at frictional force and the many sorts of it in this post.
