When it is sitting still or motionless

The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.

Explanation:

Explanation:

A force,

F

, applied to an object causes an acceleration,

a

, which we know from Newton's 2nd law:

F

=

m

⋅

a

or

a

=

F

m

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it.

Note: "force" in this discussion is to be interpreted as net force. Net force is the vector sum of all forces acting on the object.

Here, we have used Newton's 2nd law to show how it relates to his 1st law:

Newton's First Law of Motion: I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
