Answer 2

Answer:

Types of friction

Friction is defined as the force that opposes the motion of a solid object over another. There are mainly four types of friction: static friction, sliding friction, rolling friction, and fluid friction.

Methods to reduce friction:

-Make the surfaces smoother by Lubricating them or by  polishing

-Make the object more streamlined.

-Friction can be reduced by using wheels to move objects.

-Reduce the forces acting on the surfaces.

-Friction can be reduced by using ball bearing between the moving parts of machine.

-Reduce the contact between the surfaces.

-Roll the bodies instead of sliding them

Methods to increase friction:

-By applying more force to the object

- By increasing the mass of the object that is causing friction

- By creating a rougher point of contact.
