Advantages and Disadvantages of Friction

 

Advantages of Friction

 

1. We could not walk without the friction between our shoes and the ground. As we try to step forward, we push your foot backward. Friction holds our shoe to the ground allowing you to walk.

 

2. Writing with a pencil requires friction. We could not hold a pencil in our hand without friction.

 

3. A nail stays in wood due to friction

 

4. Nut and bold cal hold due to friction.

 

 

Disadvantages of Friction

 

1. In any type of vehicle such as a car, boat or airplane-excess friction means that extra fuel must be used to power the vehicle. In other words, fuel or energy is being wasted because of the friction.

 

2. The Law of Conservation of Energy states that the amount of energy remains constant. Thus, the energy that is “lost” to friction in trying to move an object is really turned to heat energy. The friction of parts rubbing together creates heat.

 

3. Due to the friction a machine has less frequency 100%.

 

4. Due to friction machine catch fire.

 

The last factor that can tip the scales towards reading is the problem of multitasking. “If you’re trying to learn something by doing two things at the same time, you’re less assimilating the information,” notes Willingham. Even if you are doing one thing on autopilot, for example, driving a car or washing dishes, some of your attention is occupied, and this makes learning difficult.
