Can an object be in motion if no external forces are acting on it?

yes. external forces ALTER an object's motion... but once it starts moving and has no external forces being applied on it, it will go in a straight line with constant velocity (Newton's 1st Law of Motion)

∙ 14y agoYes it is possible for an object to be in motion without any forces acting upon it. It may only be possible in theory, though, since it would be difficult to find somewhere in the universe where there are no forces (gravity, in particular) that could act upon something.
The fact is, that once an object is in motion, it will remain in motion until some force arrests (stops) the object. Therefore, the motion must continue if there are no influences from any forces. This answer, of course, assumes that you are ignoring the fact that an object in motion is a force, in and of, itself.
The Theory of Relativity would also support the above statements.

acting on it is required in order for its speed or direction to change.

When the forces acting on an object are balanced the motion of the object?
are constant
Is it possible for an object to not be in motion and still have forces acting on it?
Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.
Unbalanced forces acting on an object will change the object's motion?
Yes.
How do balance forces acting on an object affect its motion?
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
Is it possible for an object to have serveral forces acting on it and still not change its motion?
Yes. As long as the forces are equal and opposite the object will not change its motion.
Can an object in motion if no external forces are acting on it?
yes. external forces ALTER an object's motion... but once it starts moving and has no external forces being applied on it, it will go in a straight line with constant velocity (Newton's 1st Law of Motion)
How do balanced forces acting on an object affect its motion. How do unbalanced forces acting on an object affect its motion?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
Motion is produce by?
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
How do unbalanced forces acting on an object its motion?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).

When is an object travelling in an uniform motion?
It travels in uniform motion when there are no net forces acting on it.
How do unbalanced forces acting on an object affects it's motions?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
