What happens to an object if the net force is zero?

His First Law states that an object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity. Whenever a spring is stretched, if it is to remain motionless, it must experience equal and opposite forces at either end.

Is it possible for an object to move if no net force is acting on it explain?

Is it possible for an object to be in motion if no net force is acting on it? Explain. yes it is possible because when the net force is zero and acceleration is zero. so if the object has some constant velocity it continues with the same velocity until it has some external acceleration.

When the net force acting on an object is zero the forces are?

Explanation: The net force is the total amount of force acted on an object. It becomes 0 when the forces are equal, cancelling each other out (or balancing them – same thing).

Can an object move with zero acceleration?

4) a) Can an object be moving when its acceleration is zero? Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.

When no net force is applied to a moving object it still comes to rest because of its inertia?

This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest.

Can an object be moving when its acceleration is zero?

When an object remains stationary Are there forces?

It is NOT possible for just three forces to be acting upon an object and they still balance each other. A free-falling object experiences a balance of forces. Balanced forces cause stationary objects to remain at rest and moving objects to come to rest.

Can you be in motion and have your net force equal to zero?

Yes, the net force can be zero on a moving object. If the net force is zero, then the object’s acceleration is zero, but its velocity is not necessarily zero.

Can the speed of an object change if the net work done on it is zero explain?

Work is the change in kinetic energy, so if work is zero, kinetic energy is fixed and speed is fixed. Velocity can change by having the particle change direction. Velocity need not be zero, and therefore displacement need not be zero.

Can an object move when there is no force applied to it?

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it. Note: “force” in this…

Does the velocity change when there is no force?

Yes! A force, F, applied to an object causes an acceleration, a, which we know from Newton’s 2nd law: Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing.

What is the net force of an object?

It is commonly said that in each situation there is a net force acting upon the object. The net force is the vector sum of all the forces that act upon an object.

Is there an unbalanced force in each situation?

In each of the above situations, there is an unbalanced force. It is commonly said that in each situation there is a net force acting upon the object. The net force is the vector sum of all the forces that act upon an object.
