Question

When an unbalanced force acts on an object,

Answer 1

When balanced forces follow up on an object, the object won't move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

Answer 2

Answer;

The object accelerates

When an unbalanced force acts on an object, the object accelerates.

Explanation;

• If the forces acting on a budget are balanced, the motion of the object does not change. The net force acting on the object will be zero.
• When the net force acting on an object is not zero, the forces acting on the object are unbalanced forces. Unbalanced forces cause objects to change their motion, or accelerate.
• Balanced forces on an object do not affect the motion of an object while the unbalanced forces change the motion of an object.
