An object experiences a net zero external unbalanced force. Is it possible for the object to be traveling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If not, provide a reason.

An object experiences a net zero external unbalanced force. Yes, it is possible for the object to be traveling with a non-zero velocity when the net external force on it is zero. Yes, even when there is no net external force acting on an item, it can nonetheless move with a non-zero velocity. As long as there is no outside, unbalanced forces acting on an object, Newton's first law of motion states that it will continue to move in the direction it is traveling at a constant speed.

Some external unbalanced force must act upon the object in order to alter its velocity. For example, a raindrop descends at a constant speed. The upthrust and air velocity counteract the weight of the drop. The plunge is subject to zero net force.

Meaning of velocity

Velocity is the rate at which the position of an item shifts with respect to time and a frame of reference. The act of traveling swiftly in one direction is all that velocity is, despite its sophisticated appearance. The definition of velocity calls for both magnitude (speed) and direction because it is a vector quantity. The meter per second is the SI equivalent (ms-1). If a body's velocity varies in either direction or magnitude, it is said to be accelerating.

Initial and Final Velocity

When gravity first exerts a force on an object, its initial velocity defines how quickly the object moves. The final velocity, on the other hand, is a vector number that gauges a moving body's speed and direction after it has reached its maximum acceleration.

Summary:

An object experiences a net zero external unbalanced force. Is it possible for the object to be traveling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If not, provide a reason.

A net zero external unbalanced force acts on an object. When the net external force on an object is zero, it is nevertheless conceivable for that object to be moving at a velocity other than zero.
