An object experiences a net zero external unbalanced force. Isit 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 no, provide a reason.


Given:

An object experiences a net zero external unbalanced force.


To do:

  1. To check whether it is possible for the object to be traveling with a non-zero velocity.
  2. Also, we have to state the conditions that must be placed on the magnitude and direction of the velocity if it is possible for the object to be traveling with a non-zero velocity.
  3. To provide a reason if the answer is no.

Solution:

Yes, it is possible for an object to be traveling with a non-zero velocity if the object experiences a net zero external unbalanced force. let us know how it is possible and what conditions must be placed on the magnitude and direction of the velocity:

Condition for traveling with a non-zero velocity:

Newton's first law of motion states that an object is at rest or moving with a constant velocity in a straight line and will, remain at rest or moving until an external force is acted upon the object. it is the external force unbalanced force that brings an object into motion from the rest and vice versa. if the object is experiencing a non-zero external unbalanced force then the object will remain in its initial position$(either\ in\ rest\ or\ into\ motion\ with\ non-zero\ velocity)$

Conclusion:

An object may be traveling with a constant $(non−zero)$ velocity in the same direction as in the beginning or maybe at rest $(not\ moving\ at\ all)$ if it is experiencing a net zero external unbalanced force.
