What are the beneficial and harmful effects of friction?

Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful so it may be necessary to decrease or increase friction.

How can friction be unhelpful?

Friction can also be unhelpful. If you do not lubricate your bike regularly with oil the friction in the chain and axles increases. Your bike will be noisy and difficult to pedal. When there is a lot of friction between moving parts energy is transferred to the surroundings causing heating.

What gives friction a bad reputation?

Since friction is a resistive force that slows down or prevents motion it can be a nuisance because it can hinder motion and cause the need for expending extra energy. Friction can also cause parts in contact to heat up and can cause parts in contact to wear out.

What happens with too much friction?

Friction can work for or against us. For example putting sand on an icy sidewalk increases friction so you are less likely to slip. Too much friction between moving parts in a car engine can cause the parts to wear out.

  • Noise production in machines is irritating as well as leads to energy loss.

What are three everyday activities you Cannot do without friction?

What are 3 everyday activities you couldn’t do without friction?
  • Sneezing and still staying in the same place.
  • Belt-pulley drive.
  • Ease in normal walking.
  • Holding a bottle for drinking water.

Where is friction a nuisance in everyday life?

However friction can also be a real nuisance. If a door hinge squeaks the noise is caused by friction. The moving parts of a car’s engine rub against each other and can stick together causing the engine to seize and to stop working. Using oil in a car’s engine protects the parts from friction.

What happens if there is not enough friction?

Explanation: Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything.

What are the disadvantages of friction in sports?

Friction is also the reason for decreased speed of playing objects on ground as well due to resistance by uneven ground. Sliding or movement of fallen person causes increased injury due to friction as it causes heat and resistance to movement of body. Wear and tear of ball and other objects is also a common example.
