What is the net force on an object with constant velocity?

Constant velocity = 0 Acceleration = 0 therefore force = 0


What is the net force on a book that is being pushed along a desk at a constant velocity?

If the velocity is constant (not changing) then the net force is 0. Likely there is a pushing force that is equal and opposite of the force of friction.


Does net force equal velocity?

No. Net force is measured in Newtons, while velocity is measured in m/s. A net force can change an object's velocity.


What can zero net force do to an object?

Zero net force on a object means that the velocity of the object stays constant (this includes 0, when the object is not moving). Lets look at Newton's 2nd law of motion: Fnet=ma An object can never have a 0 mass (then it wouldn't exist). Therefore, the acceleration has to be 0 for the net force to be zero. Recall at acceleration is the change of velocity over time. In order for the acceleration to be zero, the velocity has to be constant. If the object is at 0 velocity (not moving), the object would remain unmoving when a net force of 0 is applied to it. If the object is moving at a certain velocity, it would remain at that velocity. Therefore, a zero not force cannot do anything to an object.


How does the net force on an object determine the motion of the object?

If there is a net force of 0 acting on an object then the object is either stationary or moving at a constant velocity. If the net force is not zero the object will accelerate in the direction of the net force.


If the net force acting on an object is 0 can you conclude that the object is at rest Why or why not?

no you cannot prove it is at rest since it may be moving at constant velocity. Constant velocity has no acceleration, hence no net force


What is the net force of an 1850 kg car moving to the right at a constant velocity of 1.44 m per s?

It is 0 N because it's moving at a constant velocity so the acceleration would be 0. Net Force = m x a so Net Force = 1850 kg x 0 m/s/s


What is the net force on an object moving at a constant velocity?

The net force on an object moving at a constant velocity is zero.


If a car is accelerating downhill under a net force of 3674 N what additional force would cause the car to have a constant velocity?

An additional force of 3674N in the opposite direction, making the net force 0N, would provide constant acceleration. Since a = F/m, if F = 0 then a = 0, and constant velocity is when a = 0.


What is the net force on an object at its terminal velocity?

Since the falling body is at terminal velocity, there is therefore no net force acting on it, otherwise it would change velocity.


What happens to the velocity of a skydiver when the force due to gravity and the frictional force of the air balance?

When both forces are equal and opposite in direction the net force becomes 0 Newton. The velocity will be constant.


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.


If an object is moving at constant velocity what happens to the net force?

If the object is moving at constant velocity, that's an indication that the net force on it is zero.


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.



What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?

If the velocity is constant (no acceleration), the net force is zero.


When the net force of an object is not 0 the forces on the object are what?

The forces would be unbalanced resulting in a change in velocity and speed.


What happens when Net force is zero?

F=ma. F=0, a=0. The object is either moving a constant velocity or not moving at all.


What forces have to be balanced for terminal velocity to be reached by an object?

For an object in freefall, terminal velocity is reached when the drag force becomes equal and opposite to the force of gravity. This creates a net force of 0, resulting in no further acceleration.


How would you describe the motion of an object when the net force is zero?

Either it is going in a straight line at a constant velocity or it is standing still (constant velocity of 0).


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


A feather with no net force on it maintains constant?

In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.


What is the net force acting when it reaches terminal velocity?

Terminal velocity means that the velocity no longer changes; therefore (by Newton's Second Law), since the acceleration is zero, the force must also be zero.


What will an object do when the net force is not zero?

Accelerate. Using Newton's second law, Net Force = mass * acceleration rearranged the equation acceleration = Net Force/mass so when the force is non zero and the mass is non zero, the object will accelerate. Note: This does not mean that the object is always at rest when the force is zero, it simply means the velocity is constant (when velocity =0, the object is at rest).


When the net force is not at zero resulting in a change of motion?

Are you asking if a non-zero net force results in a change of motion? The answer is yes. Force is defined as mass times acceleration. Acceleration is the first derivative of velocity, i.e. the rate at which velocity changes. So if the net force is not zero, the net change in velocity is not zero, which says there is a change in motion.
