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.

Must an object always have the same motion?

No, of course not! We ourselves we change our motion!


What happeneds to an object at rest if no other forces acts on it?

An object at rest will remain at rest due to Newton's First Law of Motion, which states that an object in motion stays in motion unless acted upon by an external force. Without any external forces acting on it, the object will continue to stay stationary.


Is it possible for an object to not be in motion and still have forces acting on it?

Yes, it is possible for an object to not be in motion and still have forces acting on it. This situation could occur if the forces acting on the object are balanced, resulting in a state of equilibrium where there is no net force causing motion.


What is acting forces?

Acting forces refer to the forces that are currently affecting an object or system. These forces can be external, such as gravity or friction, or internal, like tension or compression within a structure. Understanding acting forces is important in analyzing the motion and stability of objects.


How are external forces related to internal forces?

External forces act on an object from outside its system, while internal forces arise from interactions within the system itself. External forces can change the state of motion of an object, while internal forces contribute to the object's stability, structure, and internal interactions. The overall behavior of an object is determined by the net effect of both external and internal forces acting upon it.

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)


Must an object always have the same 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.

What happens to a system when there are no external forces acting on it?

If there are no external forces acting on a system, it will remain in its current state of motion or rest. This is described by Newton's first law of motion, which states that an object will continue in its state of rest or uniform motion in a straight line unless acted upon by an external force.


How are external forces related to internal forces?

External forces act on an object from outside its system, while internal forces arise from interactions within the system itself. External forces can change the state of motion of an object, while internal forces contribute to the object's stability, structure, and internal interactions. The overall behavior of an object is determined by the net effect of both external and internal forces acting upon it.


What happens when an object in a vacuum has no external forces acting upon it?

When an object in a vacuum has no external forces acting upon it, it will continue to move at a constant velocity in a straight line due to the absence of any opposing forces like friction or air resistance. This is known as Newton's first law of motion.


Do all forces acting on an object result to its motion?

Not necessarily. Forces can act on an object even if it is not in motion, causing it to accelerate or just balance out other forces. The net force on an object determines its motion, accounting for all forces acting on it.
