The "field" transmits a change of environment that exerts a force on the remote object.
Electromagntic waves/ forces
electric current
forces always have to touch an object to affect it because if you lay down a small piece of paper and blow on it its going to move p.s. I'm only a 5th grader
2 forces that push or pull each other without touching an example is...when 2 magnets are put together they pull ( or push ) each other with out TOUCHING!! ;)Hope you understand! 8)
Linear forces.
Electromagntic waves/ forces
Iron, Nickel and cobalt are attracted to magnets, these are field forces because they act on an object without touching it
electric current
A pop can can move without touching it through external forces such as wind blowing it, vibrations from music or sound nearby, or a change in temperature causing it to expand or contract and move on its own.

Non-contact force are the force that can cause or change motion of an object without actually touching it. Few examples are--- Gravity of the earth, Magnetic forces etc.Hope you got the answer,Cheers!
Force of gravity and natural force act on an object without touching it. <><><> Besides gravity, magnetism, and radiation, such as infrared light.
It is changing force

Friction force. [opposite force]
i dont know
Once the football is in air, assumed quiet, it is acted upon by at least two forces -- gravity and air friction/drag.
