there are two types of forces
1 contact forces : These are those types of forces when two objects interact with each other; they have a physical contact with each other.
2 non contact forces: These types of forces happen when two interactive objects are not in physical contact with each other; yet they are able to push or pull.
Examples of contact forces :Frictional Force Tension Force Normal force etc.
Examples of non contact forces: gravitational force magnetic force etc
(1)Frictional force: As an object moves across a surface it causes friction. Friction force can be sliding or static. Friction depends upon the nature of the two interacting surfaces. Friction opposes motion .
(2) tension force:A force that is transmitted through a string, rope, cable or wire when it is pulled tightly by the object on the opposite end is a tension force.
(3)normal force:This is the force exerted upon an object that is in contact with another stable object. Usually a normal force is applied horizontally between two objects in contact.
(1) gravitational force:this is attractive force .This is the force by which the Earth or moon or other massively huge objects attract another object towards them.all the objects are attracted towards the earth .
(2) magnetic force:This is a push or pull exerted by a magnet. The force of attraction between an object and a magnet is called magnetism. All magnets have north and south poles. This force is the attraction or repulsion that arises between electrically charged particles due to their motion.
(3)electrical force:. It is a force that exists between all charged particles.
