Question

List 3 ways by which friction can be decreased.​

Answer 1

1. Greasing and using lubricant help to decrease friction in material.
2. Smoothing and removing grips also helps to decrease friction
3. Reducing the contact between the surface

Hope it's helps....

Answer 2

Answer:

These are the three ways friction can be decreased -:

1) using a lubricant film between moving parts.

2) using low friction materials, such as Teflon.

3) reducing surface roughness.

4) decreasing the contact force (perpendicular to direction of moving) between moving parts
