Question

Roban covered a ramp with different materials and measured how far a wooden block slides on each surface before coming to a halt. Here are his results. Identify which is the smoothest surface and roughest surface. Give reason in each case. (12++1+1) How far the block slide Type of surface after being pushed sandpaper glass wood plastic cardboard 50 cm 500 cm 100 cm 300 cm 90 cm​

Answer 1

Answer:

Friction exist based on the relative motion between two surface sliding surface. ... When a surface is smooth, there is little or no resistance to motion when another smooth surface glides over it. However the result will be different if one surface is smooth and the other is rough.

Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth

Hence frictional force more in smooth surface
