Friction occurs between two rough surfaces. Be sure that if there are perfect surfaces, there will be no friction. The item you use is as heavy as you want.

In the kinetic friction, rough surfaces feel less irregularity as they slide over each other. It can even be calculated mathematically by taking the RMS value of the roughness field. This is given as a friction coefficient. However, more effort is needed to move a stationary object. The reason for this is that the coefficient of friction is higher in stationary bodies.

You can do a little experiment right away. Try to push a heavy object in a roughly place. You will feel that you can move the object more easily when you perform the move the object.
