Friction is a/an evil or foe
Answers
Friction is a friend and foe
Answer:
Friction although is necessary, can be excessive at times. Most machines require repair and maintenance because of the frictional force. The friction between parts over time is responsible for a majority of the wear and tear in a machine. So if you’re cycling needs to get repaired, you know who to blame. The frictional force also causes most of the injuries. When you fall down, the part of your body in contact with the ground scrapes the surface as you fall. The frictional force is responsible for the wound and blood. Without friction, it would be like slipping on ice. You’d just slip and slide away. It is also responsible for our cars and vehicles slowing down. When you are moving, you experience frictional forces due to multiple sources. The friction between you and the ground, the frictional force between you and the air you are moving through. Without frictional force, you’d just have to pedal your cycle once or twice and you’d keep going on and on. Thus, when we are moving, we waste a lot of energy overcoming the frictional force opposing our motion.
Even though the frictional force is a huge pain in the neck, life as we know it would have been impossible without it. Not to mention how friction holds our skyscrapers in one piece or how friction helps us turn the pages of our books. In the end, even though it makes us waste a lot of energy, causes a lot of pain as wounds and spoils our machines, life without friction is not a life worth living. The energy we waste overcoming frictional force in our daily lives is a price definitely worth paying.
