Question

what are forces? explain the types of forces.

Answer 1

Force is defined as the pull or push which produces or tends to produce a change of state of rest or of uniform motion , its direction or shape of the body . It is a vector quantity .

Types of Force

1) APPLIED FORCE :- An applied force which is applied to an object by a person or another object .

2) NORMAL FORCE :- The normal is the support force exerted upon an object which is in contact with another stable object .

3) FRICTION FORCE :- Friction is the force resisting the relative motion of solid surfaces , fluid layers and material elements sliding against each other .

4) TENSION FORCE :- The force exerted by a robe , cable , chain etc . is called the force of tension .

5) AIR RESISTANCE FORCE:- This drag force is always opposite to the objects motion and unlike Friction between solid surfaces , the drag force increases as the object moves faster . Air resistance , also known as drag .

6) SPRING FORCE:- The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it .

Answer 2

Basically, there are two types of forces, contact forces, and non-contact forces. Gravitational forces, electric forces, magnetic forces, nuclear forces, frictional forces are some examples of forces.
