AIM = To show the rough surfaces offer great friction than Smooth surfaces
Material Required a brick, a book, a string and a spring balance.
Crocedure = First Tie a string with a brick and also attach a hook to it then attach to the hook. Now place this smooth surface and pull this spring balance arrangement on a arrangement and keep increasing the farce All the from brick moves and note down the unit spring balance and then do this same process on rough surface and also note down the unit
Observation = The spring balance will show greater unit on the smooth surfaces. rough surface thean
Conclusion= This shows that rough surfaces ofer greater friction than smooth surfaces.
