friction can be reduced by using​

Answer 1

Answer:

Explanation:

greasing and using wheels

i hope my answer helps u !!!!!!!!!!!!!!!!

Answer 2

Answer:

1) By polishing the surface, as polishing makes the surface smooth.

2) When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

3) For objects that move in fluids such as boats, planes, cars, etc, the shape of their body is streamlined in order to reduce the friction between the body of the objects as the fluid.

4) Using lubricants such as oil or grease can reduce the friction between the surfaces.

5) One more good example of this is a ball or wheel. They roll to help reduce friction. Another way to reduce friction is with a lubricant like grease or oil.

6) Machines and engines use grease and oil to reduce friction and wear so they can last longer.

i hope this helps you

HAVE A GREAT DAY!!
