Definition

A force field is a region of space in which an object experiences a non-contact force. Examples include gravitational fields, electric fields, and magnetic fields.

5 Must Know Facts For Your Next Test

1. A force field is characterized by the distribution of forces at each point within the field.
2. The strength and direction of a force field can be represented by vectors.
3. In a gravitational field, the force acts on objects with mass; in an electric field, it acts on charged particles.
4. The concept of a force field helps explain how forces can act over a distance without physical contact.
5. Force fields are essential for understanding phenomena such as planetary orbits and electric circuits.
