Relative motion
Anytime that the surface of two materials are in contact. There does not have to be motion to have friction.
yes -edict- _______________ Yes, Friction is surface resistance to relative motion, as of a body sliding or rolling.
The force that opposes relative motion btwn two surfaces in contact with each other
friction is the force resisting the relative motion of solid surfaces,fluid layer,or meterial elements in contact
The direction of friction is always opposite to the direction of relative motion of two bodies in contact.For example :in rolling motion of sphere the relative motion of the sphere (at the point of contact between sphere and ground)with respect ground is backwards, and hence friction acts in forward direction ,there by causing motion .
Relative motion
Friction wasn't invented, it is an interaction between objects : "Friction is the force resisting the relative lateral motion of two solid surfaces in contact, or a solid surface in contact with a fluid"
Anytime that the surface of two materials are in contact. There does not have to be motion to have friction.
it is because of friction. friction is a force that opposes the relative motion of two surfaces in contact.
yes -edict- _______________ Yes, Friction is surface resistance to relative motion, as of a body sliding or rolling.
Frictional force is a contact force which opposes relative motion.
The force that opposes relative motion btwn two surfaces in contact with each other
the static friction force curse McGinity
* The rubbing of one object or surface against another. * Conflict, as between persons having dissimilar ideas or interests. * A force that resists the relative motion or tendency to such motion of two bodies in contact.
friction is the force resisting the relative motion of solid surfaces,fluid layer,or meterial elements in contact
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
The direction of friction is always opposite to the direction of relative motion of two bodies in contact.For example :in rolling motion of sphere the relative motion of the sphere (at the point of contact between sphere and ground)with respect ground is backwards, and hence friction acts in forward direction ,there by causing motion .
