5. Does the force of friction vary with(a) weight of the block?(b) change in the conditions of surface incontact?(c) area of contact? |

Answer» a) Friction is due to the weight of the object and the coefficient of friction. The coefficient is a number that tells you how much friction you would expect between pairs of surfaces.Force friction= weight x coefficient of frictionSo as the weight increases so does the amount of friction. |
