To make a body move from rest, external force is necessary. Once it starts moving, it will continue to do so until external forces act on it. So for an object to be in motion no force is required.
I just learned this, just because there is not force acting on it doesn't mean that it stopped moving. Although Ibelieve that a force is always acting on an object either way. To start or to stop.
Yes.
Newton's first law of motion tells us that, ...objects in motion stay in motion...unless acted upon by an external force. when an object is moving, and no force is applied to it to hinder its movement, it will continue in the same direction and at the same velocity.
NO.
A force called centripetal force is needed for an object to round a curve.
however, in order for an object to star moving an unbalanced force is required. this force may be gravity tension,a push,etc.
No. Acceleration is defined as any change in the speed or direction of motion.
In Newtonian (classical) physics, no.
definitely not
are constant
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.
Yes.
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.
Yes. As long as the forces are equal and opposite the object will not change its motion.
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)
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).

It travels in uniform motion when there are no net forces acting on it.
