To determine whether an object moves easier over a smooth or rough surface, you need to understand the concept of friction.

Friction is the force that resists the relative motion between two objects in contact. When an object moves across a surface, friction acts in the opposite direction of the motion, making it harder for the object to move. The roughness or smoothness of a surface affects the magnitude of friction.

Generally, an object moves easier over a smooth surface compared to a rough surface. This is because a smooth surface has less irregularities and fewer obstacles for the object to overcome. Smooth surfaces allow for less friction to develop, resulting in easier movement of objects.

To experience this firsthand, you can conduct a simple experiment. Take an object such as a book and try pushing it across a smooth table or a rough carpeted floor. You will notice that it requires less force to move the book on the smooth table as compared to the rough carpeted floor.

It's worth noting that the type of object and the nature of the surface also play a role. For example, some objects, such as wheels on a car or ball bearings, are designed to minimize friction and roll more easily on any surface.

In summary, objects tend to move easier over a smooth surface compared to a rough surface due to the lower amount of friction encountered.
