When an unbalanced force acts on an object, it causes the object's velocity to change. Velocity is the rate of change of displacement, so when an object's velocity changes, its path will also change.
When an unbalanced force is applied to an object, the object will accelerate in the direction of the force. The greater the unbalanced force, the greater the acceleration will be.
The direction of an unbalanced force can be changed by changing the direction of the force. For example, if you push a ball with your hand, the ball will roll in the direction that you push it. If you change the direction of your push, the ball will roll in a different direction.
The effects of unbalanced forces are important in many different situations. For example, the force of gravity pulls objects toward the Earth, which is why objects fall to the ground. The thrust of an airplane's engines pushes the airplane forward, which is why airplanes fly.
