An unbalanced force causes a change in either the speed or the direction of an object’s motion.

An object moves with a uniform velocity when the forces acting on it (pushing force and frictional force) are balanced, resulting in no net external force.
The common misconception is that an object maintains its motion under the continuous application of an unbalanced force, which is incorrect.
We need to start pedaling again to counteract the friction forces and provide the necessary force to keep the bicycle moving.
When we stop pedaling, the bicycle begins to slow down due to the friction forces acting opposite to the direction of motion.
When the children push the box with a force greater than the friction force, there is an unbalanced force, causing the box to start moving.
The box still does not move because the friction force increases to balance the increased pushing force.
The friction force arises due to the interaction between the bottom surface of the box and the rough surface of the floor.
The box does not move because of friction acting in the opposite direction to the push, which balances the pushing force.
Unbalanced forces cause an object to move in the direction of the greater force, thus bringing the object into motion or changing its state of motion.
