Chapter 23, Problem 1PQ

What is the difference between a contact force and a field force? List all the forces presented in Chapters 1 through 22. Which are field forces? Which are contact forces? Which forces are macroscopic manifestations of the electromagnetic force? What does that tell you about contact forces? Explain your answers.

Expert Solution & Answer

To determine

The difference between a contact force and a field force with example and the forces which are macroscopic manifestation of the electromagnetic force.

Answer to Problem 1PQ

The object has to be in direct contact for contact force not for field forces. Normal force, buoyant force, spring, friction are examples of contact forces and gravity is for field forces.

Explanation of Solution

For a contact force between two objects, the object must be in direct contact. If the objects are not in direct contact, the contact force cannot be exerted. The normal force, buoyant force, spring, friction are examples of contact forces. These forces are macroscopic manifestation of electromagnetic force.

The field forces can be exerted even if the objects are not in direct contact. It can even exist in a very large separation between the objects. Gravitational force is an example of field force.

Conclusion:

The object has to be in direct contact for contact force not for field forces.
