    Friction
In summary, friction is a force that resists the motion of objects when they come in contact with each other. It can either help or hinder the movement of objects, depending on the situation. Little hills and valleys on the surfaces of objects are responsible for creating friction. The atomic theory of friction is considered the better theory, as it explains friction as being caused by the interaction between atoms. Understanding friction can benefit us by allowing us to improve and control the movement of objects, as well as develop better materials and lubricants to reduce friction and increase efficiency.

what is up with the theroy of little hills and valleys being used to describe friction! in order for this to work you need friction!
There has to be a better theroy! any ideas!

Why do you need friction to explain friction? Just e/m interaction of atoms (=attraction and repulsion between electric charges) would do it.

Truth is, friction is not well understood by anybody. A surprising state fo affairs, considering it is one area of physics wherein greater understanding could yield tremendous amounts of practical application.
 

1. What is friction?

Friction is a force that resists the motion of objects when they come in contact with each other.

2. How does friction affect the movement of objects?

Friction can either help or hinder the movement of objects. It can be useful for maintaining grip or slowing down objects, but it can also cause wear and tear and reduce efficiency.

3. What are little hills and valleys in relation to friction?

Little hills and valleys refer to the microscopic irregularities on the surfaces of objects. When two objects come in contact, these tiny hills and valleys interlock and create friction.

4. What is the better theory of friction?

The better theory of friction is the atomic theory of friction, which explains friction as being caused by the interaction between the atoms on the surfaces of objects.

5. How does understanding friction benefit us?

Understanding friction allows us to improve and control the movement of objects. It also helps us develop better materials and lubricants to reduce friction and increase efficiency.
