It is in equilibrium.
Yes, but an object with net force of zero may still be moving. The net force is zero if the object is not accelerating.
Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.
Yes.
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
Not accelerating. It could be stationary or moving at a constant speed.
It will keep moving with a constant velocity since zero net force means no acceleration. If the object is at rest, it will just stay at rest.
You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
Yes, but the net force is ZERO! If an object is moving at constant velocity, the sum of the forces acting upon it is zero. When an object is motionless, its constant velocity is zero. If at any time the sum of the forces -- sometimes called the net force -- is non-zero, the object will accelerate in the direction of the resultant force.
That is correct. Any non-zero force would cause an acceleration (change of velocity).
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
