TYPES OF FORCE

Sponsored links

FORCE IS OF FOLLOWING TYPES:
  • MASCULAR FORCE
  • MECHANICAL FORCE
  • MAGNETIC FORCE
  • GRAVITATIONAL FORCE
  • FRICTIONAL FORCE
MASCULAR FORCE: If we want to lift a weight we will use our muscle or to lift a heavy object we use our muscle so the force exerted by the muscle of the body is called muscular force.

MECHANICAL FORCE: The force produced by the machine is called mechanical force. for example we switch on any button of any washing machine it will wash the cloth.

MAGNETIC FORCE: If we take a bar of magnet and bring the magnet near the iron nail the iron nails get attracted toward the magnet and this force exerted by magnet is called magnetic force.

GRAVITATIONAL FORCE: If we through any ball or any piece of stone it will come back to ground it mean earth attracted the ball and stone and any other thing toward itself and this force of attraction exerted by earth on all the things is known as gravitational force.

FRICTIONAL FORCE: If we roll a ball on the ground it will stop after traveling some distance it mean there is some force which make the ball stop from its motion and this force is known as frictional force so frictional is defined as the force which opposes the motion of one body over another when the two bodied are in contact with each other.

ELASTIC FORCE:When we stretched a rubber band its shape will be change, and when we remove the force, it will come back to its original position, so the force which changes the shape of the body temporary such that the body regains its original shape after removing the force is called elastic force.

ELECTROSTATIC FORCE- The force exerted by charges at rest, for example when you rub the comb on dry hairs, the charge present on the board comes in motion and starts conduct electricity that's why the hair gets attracted toward the comb.


ELECTRICAL FORCE -  The force exerted by charges in motion, for eg- electricity flows in any conductor
