Answer:

A non-contact force is a force which acts on an object without coming physically in contact with it.[1] The most familiar non-contact force is gravity, which confers weight.[2] In contrast a contact force is a force applied to a body by another body that is in contact with it.[2]

All four known fundamental interactions are non-contact forces:[3]

Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on each bo the distance between them.

Electromagnetism is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays. Electromagnetism mediates all chemical, biological, electrical and electronic processes.
