Question

if a pair of forces are unbalanced, the motion of that object will ______. be changed cancel out non - existent be unchanged

Explanation:

According to Newton's first law of motion, when forces acting on an object are unbalanced, there is a net force. This net force causes a change in the object's velocity (either in magnitude or direction), which means a change in its motion. Balanced forces (where forces cancel out) result in no change in motion. The term "non - existent" is not relevant in the context of force - motion relationship for an object with unbalanced forces acting on it.

Answer:

be changed
