Physic- 21
Frictional force can be both useful and nuisance:Friction between the ground and our feet or shoes helps us to walk/run. Without friction, we might just be probably walking and slipping or just walking on the same spot over and over again. Nuisance frictional forces such as wear and tear. Or wearing down machines in factories. Friction also produces heat. However, it's wrong to say that heat produced by friction is bad. This is because by rubbing our hands together and producing heat, may warm us up during cold weathers. --------------------------------------------------------------------------- Write down 3 ways on how friction can be reduced: 1) Using lubricant: By using this, the object that is contacting with the other surface would be in a sense 'smoother'. Like windows. 2) Ball Bearings: when we transport heavy loads by putting ball bearings below to make it easier to move. 3)Use of wheels and rollers: Roller blades can be in an instance. It reduces friction because there's lesser contact between the ground and the wheels. Sophia(: |
