Question

How can one object affect the motion of another without touching it?​

Answer 1

By non-contact forces (e.g. gravitational force and electric force)

Explanation:

In order for an object to exert a force on another object, the two object can also be not touching each other. In fact, there exist some non-contact forces in nature.

Concerning macroscopic objects, the two main non-contact forces acting between objects are:

- The gravitational force: this force is exerted between every object that has mass. It is always attractive, and its magnitude is given by

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

- The electric force: this force is exerted between objects that have electric charge. It can be either attractive or repulsive, and its magnitude is given by

$F=k\frac{q_1 q_2}{r^2}$

where:

$k=8.99\cdot 10^9 Nm^{-2}C^{-2}$ is the Coulomb's constant

$q_1, q_2$ are the two charges

r is the separation between the two charges
