What are advantages of force?

It is becomes difficult to walk on a slippery road due to low friction. We can not fix nail in the wood or wall if there is no friction. A horse can not pull a cart unless friction furnishes him a secure Foothold. We can write on a paper or on a board.

What are 5 disadvantages of friction?

Disadvantages of friction:

  • Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat.
  • Opposes motion, hence more energy is needed to overcome friction.
  • Noise production in machines is irritating as well as leads to energy loss.

What are the advantages and disadvantages of force of friction?

Advantages and disadvantages of friction

  • Friction helps us to walk, turn and stop.
  • Friction helps to wear cap, ring, and belt.
  • Friction help in the transfer of energy.
  • Friction helps in making fire.
  • Friction helps to hold onto objects.
  • Produces unwanted heat.
  • Reduces efficiency of machines.
  • Eco-hazard.

What are the three disadvantages of friction?

Three disadvantages of friction are :

  • Friction produces heat which damages the moving parts of a machine.
  • Friction produces wear and tear on the contacting surfaces. This reduces the life of machine parts, tyres and shoe soles.
  • A lot of energy is wasted in overcoming the friction before an object starts moving.

What are the disadvantages of physics?

DISADVANTAGES :

  • Though we welcome these blessing of science, we have to consider the darker side of the picture also.
  • Machines have led to unemployment.
  • They have polluted water and atmosphere.
  • Factories have led to slums where human beings live in squalor.

What are the disadvantages of friction class 11?

Disadvantages of Friction:

  • Friction produces unnecessary heat leading to the wastage of energy.
  • The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.
  • Forest fires are caused due to the friction between tree branches.

What are the advantages and disadvantages of friction in sports?

With friction of feet/ shoes on the surface, help to speed. Frictional forces help to move the object in the speed. For example, spikes are used by the athletes to run fast. Wastage of energy: Excess of friction means extra energy, thus energy is being wasted.

What are the advantages and disadvantages of friction in our daily lives?

Advantage:Friction is help use to move one place to another place . Disadvantage:when the friction come on walking and running they work on the sole of shoes and the a sole of shoes is decreased by running and walking so, it is costly. Advantages of friction : Friction helps us to walk on the ground.

What are the disadvantages of friction class 9?

List the disadvantages of friction

  • Friction produces heat that causes objects to wear out.
  • Friction makes work tedious.
  • Friction also causes sparks, overheating and machine breakdown.
  • Friction reduces speed.
  • Friction can also make speeding objects to tumble down and cause accidents.

What is the disadvantages of science?

Science has been responsible for pollution and given us the nuclear bomb that threatens our very existence. Science is not intrinsically good or bad. It is a way to acquire knowledge in a systematic way. The disadvantage of new mobile phones is too many can communicate with us all at the same time.
