Question

Explain any 3 methods of reducing friction.​

Answer 1

Answer:

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

Answer 2

Friction is the resistance a surface or an item encounters when moving across another. Friction is the resistance that two surfaces provide when they move together. When a ball is tossed, for example, it travels a certain distance before coming to a complete halt.

The strategies for minimizing friction are as follows:

• Boats, aircraft, vehicles, and other items that move in fluids have streamlined bodies to decrease friction between the object's body and the fluid.
• The surface can be polished to make it smoother and minimize friction.
• Friction between the surfaces can be reduced by using lubricants like oil or grease.
• The friction between the rolled object and the surface can be minimized by employing ball bearings when things are rolled over the surface.
