The two main types of force are:

• Contact Forces : These forces occur when two objects physically touch each other. Examples include frictional force, normal force, applied force, tension force, and air resistance. Contact forces require direct physical interaction between objects

• Non-Contact Forces (also called field forces): These forces act over a distance without physical contact. Examples include gravitational force, magnetic force, and electrical force. These forces create fields around objects that can exert influence on other objects within those fields

In summary, forces are classified as either contact forces, which involve physical touch, or non-contact forces, which act at a distance.
