Answer:
The orientation of an object does not affect its friction when moving along a surface because friction is a force that acts parallel to the surface and opposes the relative motion between the object and the surface. Friction depends on the nature of the surfaces in contact and the normal force, which is the perpendicular force exerted by the surface on the object. The orientation of the object does not change the magnitude or direction of the normal force or the nature of the surfaces in contact.
When an object is placed on a surface, the normal force is exerted perpendicular to the surface, regardless of the object's orientation. The frictional force acts parallel to the surface and opposes the motion or tendency of motion between the object and the surface. The coefficient of friction, which depends on the materials in contact, determines the magnitude of the frictional force.
In other words, the orientation of the object may change its appearance or the forces acting on it in different directions, but it does not impact the frictional force as long as the normal force and the nature of the surfaces remain the same.
