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.

It’s possible under certain conditions:**
1. Uniform Motion: The object must be moving at a constant velocity.
2. Balanced Forces: While there might be multiple forces acting, their combined effect results in zero net force.
3. Directional Consistency: These forces shouldn’t change the velocity’s magnitude or direction.

Explanation:
– If an object is already moving steadily with constant velocity and the forces acting on it counterbalance each other (resulting in a net force of zero), it maintains its velocity due to Newton’s First Law.
– Despite no unbalanced force causing acceleration or deceleration, the object continues with its constant velocity. For instance, this happens in space or when air resistance balances gravity during free fall (reaching terminal velocity).

Conclusion:
An object can uphold a non-zero velocity while experiencing a net zero unbalanced force by sustaining constant motion with balanced forces, allowing it to move steadily without changing its speed or direction.
