The ball is moving in a straight line, at a constant speed (which could be zero but doesn't have to be).

If there are no forces acting on an object, or there ARE some but they add up to zero, then the object is not accelerating.

Answer from: nedy82

The net force on the ball will be zero and the ball will remain in its initial state either moving or at rest.

Explanation :

We all familiar with Newton first law of motion which states, an object remains either at rest or moving with a uniform speed; until some external force hinders its motion or state. This is called law of inertia.

Now, if there are multiple force acting on a body and all of them are equal and opposite to one another then, the resultant force will be zero. This can be formulated as,

$F_{T}=\sum F_{i}=0$

Where,

$F_{T}$ - Total amount of force acting on a body

$F_{i}$ - Number of forces acting on a body

Considering a ball with multiple forces acting on it and all of them being equal and opposite, there will be no change in its state either it's in the rest position or moving in same velocity.

An atom (ours, not carroll's) consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6 nm. * if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
