Question

List some methods to reduce friction to conserve energy

Answer 1

Make surfaces smooth by grinding.

Lubrication.

Streamlined body.

Reduce pressure or weight on the object.

Reduce contact between surfaces by electrostatic magnetic levitation etc.

Use rolling friction instead of sliding friction.

Use fluid friction instead of the dry friction.

Step-by-step explanation:

Answer 2

Here are the five main ways to reduce friction:

• Using Lubricants

Definition: A lubricant is a substance that forms a thin layer between

the two surfaces in contact.

• Using Soap Solutions
• Using Ball Bearings
• Polishing Surfaces
• Improving designs
