Sliding versus Static Friction:
Friction force is the force exert by a surface as an object moves crosswise it or makes an effort to move across it. Two types of friction forces - static friction and sliding friction
Sliding friction results when an object slides across a surface. For instance consider pushing a box across a floor. The floor surface offers resistance to the group of the box. We often say that the floor exerts a friction force upon the box.
Static Friction results when the surfaces of 2 objects are at rest relative to one another and a force exists on 1 of the objects to set it into motion relative to the other object. Assume you were to push with 5-Newton of force on a large box to move it across the floor
When two particles tend to each other, their motion alters or their momentum modify because of their mutual interactions. This phenomenon is called as collision. During collision
