Question
Does friction force come into play only when solids are involved?
- Yes
- No
Hint:
The friction force comes into play when any surface that is solid, liquid, or gas gets in touch.
The correct answer is: No
No. Friction force doesn't come into play only when solids are involved.
- Friction is caused when two objects get into contact.
- The objects that involve in friction can be solid, liquid, or gas.
- The frictional force depends on the nature, shape, structure, and speed of the object.
