An object experiences a net zero external unbalanced force. Is it possible for the object to be travelling 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.
Answer
A net zero external unbalanced force means that object has balanced force.
In balanced force,
- Stationary object remains stationary
- Moving object remains moving.
Therefore,
Yes , it is possible for the object to travel with a non-zero velocity.
It is possible only if the object’s velocity remains constant - i.e.
- Magnitude of velocity doesn’t change
- Direction of object doesn’t change
