Step 1: Understand the definitions of rolling and sliding friction.
Rolling friction occurs when an object rolls over a surface, such as a wheel or ball, whereas sliding friction occurs when an object slides over a surface.
Step 2: Analyze the factors affecting friction. Rolling friction is usually influenced by the deformation of the surface and the rolling object, while sliding friction is influenced by the surface texture and the normal force.
Step 3: Compare the magnitudes of rolling and sliding friction. In general, rolling friction is significantly less than sliding friction because rolling objects do not have the same inter-surface contact as sliding objects, leading to lower resistance.
Therefore, the correct statement is that rolling friction is less than sliding friction.
