My professor gave us a question about gravity but I just have no idea how to explain it. I hope somebody will help me out as soon as possible, thanks a lot.

Question: How does gravity affect us without even touching us unlike other forces?
 
Physics news on Phys.org
Hint: Consider the analogy of an electrostatics and how electrostatics makes use of electric fields.
 
well, I still kinda don't get the correct idea, can somebody help me out?
 
The simple answer is that's just the way it is; that is, gravity doesn't have to touch us to affect us as contact forces do. If you want have a more intuitive understanding, and if you have not seen the analogy to electrostatics yet, look up gravitational field. Consider, what is a field? What does the strength of the force of gravity depend on? What does the strength of the acceleration of gravity depend on?
