Question

which of the following always causes an object to change its velocity? (1 point)
if the forces on an object became unbalanced
if the forces acting on an object are equal in magnitude and opposite in direction
if more forces began to act on an object
if fewer forces began to act on an object

Explanation:

According to Newton's first - law of motion, an object's velocity changes when an unbalanced force acts on it. Balanced forces (equal in magnitude and opposite in direction) result in no net force and no change in velocity. Just having more or fewer forces doesn't guarantee a change in velocity; it's the balance or imbalance of forces that matters.

Answer:

If the forces on an object became unbalanced
