Question

name the four ways by which friction can be minimised.​

Answer 1

Explanation:

There are a number of ways to reduce friction:

1. Make the surfaces smoother.

2. Lubrication is another way to make a surface smoother.

3. Make the object more streamlined.

4. Reduce the forces acting on the surfaces.

5. Reduce the contact between the surfaces.

Answer 2

Answer:

Methods to reduce friction

Following are the different methods that are used for reducing the friction:

1. 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.

2. By polishing the surface, as polishing makes the surface smooth and friction can be reduced.

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

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