Answer
Gravity
Explanation
The four types of fundamental forces in Universe include gravitational force, electromagnetic force, strong nuclear force and weak nuclear force. Among them, non-contact forces include gravitational and electromagnetic forces.- Gravity is a non-contact force that acts between two masses at all times and ranges. it solely depends on the mass of the objects and range between them. - Tension is a contact force that works through a stiff 'tensile medium', like a string or rope.- Friction is also contact force (often named surface forces) that fights against the movement of one body over another.This question asking us to consider the forces listed; Friction, Tension and Gravity. Out of which Gravity is a non-contact force (invisible but it can smoothly been perceived. (e.i the acceleration towards non resistive body & velocity changing into straight line motion) as there is no substantial indirect contact medium, in comparison to strings in the case of tension and surface contact in the case of friction.
