what is sliding, Static and rolling friction??????
Answers
Explanation:
Sliding friction:
The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving.
Static friction:
Static friction is a force that keeps an object at rest. It must be overcome to start moving the object.
Rolling Friction:
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-plastic effects; that is, not all the energy needed for deformation of the wheel, roadbed, etc. is recovered when the pressure is removed.
Hope it helps!
Explanation:
1.static friction is the friction force which gives object at rest .
2.sliding friction is the friction force on on the object when the object is moving over a surface..
3.rolling friction is a friction force on the object when the object rolls over a surface
