Webdecreased from 126.28 cm 2 to 80.08 cm 2. We predicted that in this experiment, the frictional force would be decreased with less contact as there would be less bonding between the surfaces and therefore less friction. When we tested how the smoothness of the surface affected friction, we tested this by changing the surface type. WebFriction is frequently portrayed in the popular media as having a ‘bad’ effect and as something to be reduced or eliminated (for example by using friction reducing oils). …

Web15 mrt. 2024 · Steps 3 to 6 are repeated with two and then three identical elastic cords as shown in Figure. For each case, the elastic cords are kept stretched until the end of the trolley and parallel to the trolley so that the … WebIf the surface is very smooth, all the molecule on the 2 surfaces are in contact and form a very large bond. It will be hard to produce motion between 2 surfaces. It's very difficult to move, so it can be reduced. It is possible to reduce Friction by filling a thin layer of lubricant between the two surfaces. head rebel backpack
