Answer

The force of friction is greater on rough surfaces than on smooth surfaces. Explanation 1. Identify Frictional Force Relationship Frictional force is generally **greater** on rough surfaces than on smooth surfaces due to increased surface irregularities. 2. Analyze Data Compare the measured frictional forces from your data for smooth and rough surfaces. Typically, rough surfaces show higher frictional force values. 3. Infer from Observations If your data shows higher frictional forces on rough surfaces, it supports the inference that friction is greater on rough surfaces.
