5 Questions
What are three ways to reduce friction?
- By using lubricants. 2. By using ball bearings. 3. By streamlining bodies of cars, aeroplanes, and ships.
How does lubricant reduce friction?
Lubricant forms a thin layer between the moving parts of a machine, preventing direct rubbing and reducing friction.
What is the function of ball bearings in reducing friction?
Ball bearings convert sliding friction into rolling friction by allowing the metal balls to roll when the machine's axle rotates.
Give an example of an object that is streamlined to reduce friction.
Cars, aeroplanes, and ships are streamlined to reduce friction.
How do small wheels help in reducing friction?
Small wheels on heavy objects help to reduce friction.
