is friction an electromagnetic force
hey adroit,
yes friction is an electromagnetic force where...
Friction is originated from electromagnetic forces and exchange forces between atoms and molecules. Electromagnetic forces and exchange forces (strong force) are two of the 4 fundamental forces, strong force, electromagnetic, weak force and gravity. Exchange force is any force that has to do with the exchange of particles. Technically all 4 forces can be classified as an exchange force.
Electromagnetic force is the force which holds the atoms together and keeps the electrons from flying off somewhere away from the atoms nucleus and also holds the atoms together to form molecules. You probably heard the phrase, “Like charges repel, opposite charges attract.” Two positive or two negative particles will repel while a positive and a negative particle will attract. Atoms are made up of neutrons (neutrally charged), protons (positively charges) and Electrons (negatively charged).
Electromagnetic force is a force that exerts on electrically charged particles
but friction is a force that resists the relative motion or tendency to such motion of two bodies or substances in contact.
FRICTION IS an electromagnetic force arising due to attraction between molecules of object and that of ground.
Certain molecules are going to attract to each other increasing frictional forces and some molecules repel reducing frictional forces. Lets look at what some call the most slippery material on earth – polytetrafluoroethylene (PTFE) or commonly referred to by its trade name Teflon®. PTFE is a long string of carbon atoms joined together with two fluorine atoms attached to each carbon atom. Fluorine, when attached to a molecule doesn't like any other molecule around it. It repels any other molecule even other molecules with fluorine atoms, hence its low coefficient of friction or slipperiness.
Good Luck!!!!!!
