Galileo deduced that objects on an inclined plane, when no external force acts on them, move with a constant speed. This observation laid the foundation for understanding motion and inertia, highlighting that no force is needed to maintain constant velocity.

If the unbalanced force is removed completely, the object would continue to move with the velocity it has acquired up to that point.
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.
