2. Graphite powder is used in some machines to ____ friction.

3. We want to reduce friction in order to increase ______.

4. To reduce friction between rotating shafts we use ______.



5. What is called the principle of ball bearings?

6. What is rolling friction?

7. Can we reduce friction to zero, explain? please answer it with honestly
dont say idont know it is urgent please​

Answer 1

Answer:

rolling friction is less than sliding friction

Answer 2

Answer:

1. Less

2. Reduce

3. Slipperiness

4. Ball bearings

5. The principle on which ball bearing works is that it reduces the friction between the machinery parts

6. The force resisting the motion of a rolling body on a surface is known as Rolling friction or Rolling resistance. Rolling of ball or wheel on the ground is an example of Rolling friction.

7. Friction can be reduced by polishing a surface or by using large amount of lubricants such as oil, water, or grease but we cannot reduce friction of zero.
