Final answer:
In physics, forces are divided into contact forces and field forces. Contact forces occur when objects are in direct physical contact, and field forces act without the need for physical contact. Example of contact forces include the force exerted by a chair or the force exerted by the floor on a person's feet. An example of a field force is gravity.
Step-by-step explanation:
In physics, forces are categorized into two types: contact forces and field forces. Contact forces result from direct physical contact between objects, such as the force exerted by a chair on a person or the force exerted by the floor on a person's feet. Field forces, on the other hand, do not require physical contact and depend on the presence of a field in the surrounding space. An example of a field force is the gravitational force that a person experiences in Earth's gravitational field.
