Length is a measurement that typically refers to the longer side or dimension of an object, usually running horizontally or vertically. It is not considered diagonal, which refers to a measurement taken at an angle across the object.
Surface area refers to the total area that covers the surface of an object or structure. To decrease surface area, you can reduce the dimensions of the object or change its shape to be more compact. To increase surface area, you can add extensions, rough textures, or indentations to the object's surface.
Friction is a force that opposes the motion of an object, so when an object moves forward, friction acts in the opposite direction to slow down the object. The force of friction is proportional to the weight of the object and the surface it is moving across.
If the bag is sliding across the countertop (i.e., the same surface of the bag is always in contact with the counter), then no. Rolling friction is only relevant when the surface of an object in contact with the surface it moves across always changes.
The surface of an object affects the aerodynamic drag: a force which acts against the direction of motion.

When pushing an object across a rough surface, the roughness creates more friction between the object and the surface. This increased friction requires more force to overcome in order to move the object. The additional force helps to counteract the resistance caused by the rough surface and allows the object to move.
Horizontally
It depends on the surface on which the object is moving, and also any other forces - such as gravity.
The center of mass of the object follows a smooth path when it spins through the air or across a flat smooth surface.
Static friction is the type of friction that requires force to start an object moving across a surface. Once the object is in motion, kinetic friction takes over to oppose its motion.
An object moving horizontally, an object resting on a surface, and an object in space with no gravitational force acting on it are not examples of free fall. Free fall specifically refers to an object falling solely under the influence of gravity.
If there is no vertical motion, then no work is done by any vertical forces.
When pushing something across a rough surface, you need to apply more force because the rough surface creates more friction between the object and the surface. This increased friction resists the motion of the object, requiring more force to overcome it. The rougher the surface, the more force is needed to move the object.
A horizontal force is applied to pull a 5.0-kilogram object by exerting a push or pull in a sideways direction. This force causes the object to move horizontally along a surface.
When friction increases, more force is required to push something across a surface. This is because the frictional force opposes the motion of the object, making it harder to move. Increasing the applied force can help overcome this resistance and move the object across the surface.
Gravity has no effect on an object moving horizontally at a constant speed unless the object is falling downward due to gravity. In that case, gravity will accelerate the object downward while it continues to move horizontally.
