Question

3. Rough surfaces offer less friction. true or false​

Answer 1

Answer:

False.

Explanation:

Smooth surface have less friction because smooth surface have less resistance than rough surface.

Answer 2

Answer:

False

Explanation:

• Because there is less friction, the car's moving parts wear less and emit less heat. Because ice has very little friction, it is simple to slip and fall on an icy day.
• Smooth surfaces produce less friction; rough surfaces produce more friction; friction produces heat; we can minimise friction by smoothing surfaces using liquids.
• Because rough surfaces have more microscopic imperfections, friction is stronger between them (hills and valleys).
• Rough surfaces offer more friction.

Hence, given statement is false.
