... Mikhael 2nd GCSE Boukraa Physics COURSEWORK What is the effect of mass on friction? PLANNING: To conduct this experiment, certain materials will be required. These include the following: 2 force meters (one that measures forces up to 5 Newtons and one that measures forces up to 10 Newtons), a mass i.e. a block of wood of about 15cm3, a table or any smooth surface, a strip of slightly grainy sandpaper and another strip of more grainy sandpaper. The experiment will be set up as shown below (fig 1). Fig 2 This experiment was set up into two sections, firstly the effect of mass on dynamic friction and then the effect of mass on static friction. Dynamic Friction: For the dynamic friction experiment, the force of friction will be read off the force meter. This is due to Newton's second law stating that Fnet = ma. When the block is being pulled along at constant speed, the acceleration
