No because if it was, nothing would ever accelerate. If you apply a net force to an object, it accelerates. The net force acting on an object is always zero if and only if it is in static equilibrium; that is, the object is not moving (rotation or translation) or moving with constant velocity.
Given that an object is in static equilibrium, you can say that the net force and moments in all three cartesian directions are zero.
An object with no force acting on it means that there are no forces present at all, while an object with a zero net force means that the forces acting on it are balanced, resulting in no acceleration. In the second case, there may be individual forces present but their combination results in a net force of zero.
Rolling friction does not reduce the net force acting against an object's motion to zero. Rolling friction is a resistive force that opposes the motion of an object moving along a surface, but it does not completely eliminate the net force. The net force is the vector sum of all forces acting on the object, including rolling friction.
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
The net force acting on an object at rest is zero. This means that all the forces acting on the object are balanced and there is no overall force causing it to move.
Not exactly. If the acceleration of the object is zero, there might be no force actingon it, but there could also be no net force acting on it. That means that there couldbe a bunch of different forces acting on it, with different strengths and directions, butthey all add up to zero.
If the net force on an object is zero, then the object is in either equilibrium (if it was at rest initially) or it is moving at a constant velocity (if it was already moving). This means there is a balance of forces acting on the object in opposite directions.
If an object is moving with constant velocity, then the net force acting on it is zero. This means that the forces acting on the object are balanced, resulting in no acceleration and a constant velocity.
If an object is at rest, the net force acting on it must be zero. This means that all forces acting on the object must be balanced and equal in magnitude but opposite in direction.
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.
If all forces acting on the object are balanced (equal), the net force acting on the object is zero.
Net force determines the motion of the object. If the net force acting on an object is not zero, the object will accelerate in the direction of the net force.
Yes, if all the forces acting on an object are balanced, the net force on the object is zero. This means that the object will remain at rest or continue moving at a constant velocity in the same direction.
