What is then net force if the velocity of an object is changing?

As velocity is changing that means acceleration/deceleration is taking place. Hence, Force will not be equal to zero. However, the direction of force will depend on the direction of velocity of body. So, it's not possible to predict whether the force will be positive or negative. The net force can not be found as the dimensions of body like mass and change in velocity are not given in the question.

What is velocity if the net force is 0?
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
What is the net force acting on a falling object when it reaches terminal velocity?
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
If an object has no net force acting on it?
it is in equilibrium.
How does zero net force affect an objects state of motion?
If there is zero net force on an object, the object will not accelerate. (It's velocity will not change.)
How does a zero net force affect an object's motion?
Zero net force has no effect on an object's motion whatsoever.
If we are told that an object has a constant velocity what can we say about the force on that object?
you can say that there is no net force on the object; that is, the net force is zero
Is it possible that body is moving with constant velocity but force acting on it is zero?
Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.

What will increase accelaration of an object that is pushed by a force?
A net force will cause an acceleration. That is to say, if a net force acts on an object, the object's velocity will change.
What is the velocity on an object with no net force?
When there is no resultant force there is no acceleration therefore the velocity will stay the same.
If an object is moving at a constant speed what do we know about the forces acting on the object?
Not much, really. If the object's direction is changing, then the velocity changes, and there are forces acting on it. The only thing we can say is that the net force acting on the object is either zero, or it is perpendicular to the movement.If the VELOCITY doesn't change, then the net force (the sum of the forces) is zero.
Why is it useful to know net force?
you can the effect of the net force in the object motion
What is net force acting on a falling object when it reaches terminal velocity?
The net force is zero.
What is net force and what does it do?
A net force is the sum (vector sum) of all forces acting on an object. If there is a net force acting on an object, the object will accelerate - its velocity will change over time.
What is the net force on an object with constant velocity?
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.
