- Grease
- Vaseline
- All of these
Hint:
Friction can be reduced by using lubricating materials or lubricants such as oil, grease, or vaseline.
The correct answer is: All of these
Friction can be reduced by using all of these.
- The friction force is created when the surfaces of two objects in relative motion touch.
- Oil, grease, or vaseline acts as lubricants which creates a layer between the surfaces that separates the layers a bit reducing the motion.
- This will decrease friction.
