Question

prepare a chart about reducing methods of friction

Answer 1

we can reduce friction on a surface by the following methods:
*By spreading powder on the surface.
* By spreading water on the surface.
*By spreading soap water on the surface.
* By spreading any liquid or any substance that has moisture will reduce the friction.

Answer 2

Friction: The force that holds the relative motion of the solids, fluids and other materials sliding against each other is referred to as frictional force.

There are four types of friction. They are,

• Static
• Sliding
• Rolling
• Fluid friction

Methods to reduce friction:

Smooth surfaces: The smooth surfaces does not resist and motion and so the friction is also reduced.

Lubrication: Lubrication enables in the easier displacement of objects.

Streamlined shape: By making the object streamlined, the fiction is reduced as it allows the flow easily.

Reduce forces: The forces acting on the materials can be reduced in order to reduce friction.

Contact surfaces: The shape of the contact surface can be made in the shape of a sphere so that it reduces the friction.
