How do you end the last paragraph of an essay?
Ending the Essay: ConclusionsConclude by linking the last paragraph to the first, perhaps by reiterating a word or phrase you used at the beginning.Conclude with a sentence composed mainly of one-syllable words.
What is the purpose of a closing paragraph?
Paragraphs. Your conclusion is your opportunity to wrap up your essay in a tidy package and bring it home for your reader. It is a good idea to recapitulate what you said in your Thesis Statement in order to suggest to your reader that you have accomplished what you set out to accomplish.
How do you discuss pros and cons?
Elements to Consider When Writing a Pros and Cons EssayChoose a debatable topic. Give equal weight to both the pros and the cons. Research your topic. Brainstorm a pros and cons list. Organize your thoughts into an outline. Write a great introductory paragraph. Fill out the details in your outline. Write your conclusion.
What are the advantages and disadvantages of friction?
Advantages and Disadvantages of FrictionFriction is responsible for many types of motion.It helps us walk on the ground.Brakes in a car make use of friction to stop the car.Asteroids are burnt in the atmosphere before reaching Earth due to friction.It helps in the generation of heat when we rub our hands.
What are the harmful effects of friction?
What are the negative effects of friction?The biggest disadvantage of friction is wear and tear that happens as a result of friction. Friction causes wear and tear in machinery parts and also cause wastage of electricity and energy. Friction causes moving objects to stop or slow down.
What are the three advantages and disadvantages of friction?
Disadvantages of friction:It always resists the motion, so extra energy is required to overcome it.It causes wear and tear of machines.It decreases the life expectancy of moving parts of vehicles.Since friction is very useful in some cases while harmful in some cases, friction is called a necessary evil.
What are the five 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.Forest fires are caused due to friction between branches of trees.
Why is friction evil?
Frictional force causes a lot of losses in general upkeep and wear and tear of machinery. Hence it is considered as a evil. But almost all crucial tasks cannot be carried out without the presence of friction. Hence it is considered as a necessary evil .
Where is friction useful?
Helpful frictional forces friction between our shoes and the floor stop us from slipping. friction between tyres and the road stop cars from skidding. friction between the brakes and wheel help bikes and cars to slow down.
Where friction is not useful?
Friction is sometimes unhelpful. Your bike will be noisy and difficult to pedal. When there is a lot of friction between moving parts, energy is lost to the surroundings as heat. Think of what happens when you rub your hands together quickly. The friction warms them up.
How does friction affect speed?
When a force makes something move, it will travel a certain distance in a measurable amount of time. This determines its speed. It will keep moving until it is acted upon by force or friction.
How can we reduce friction?
By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
Can friction be eliminated?
Frictional force cannot be eliminated completely because of the presence of microscopic plowing that occurs even with the undulated surface. The friction coefficients obtained with the undulated surfaces without lubricants were as low as those found in boundary lubrication of flat surfaces.
What are 3 ways friction can be reduced?
Methods for decreasing friction:Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.Lubrication is another way to make a surface smoother. Make the object more streamlined. Reduce the forces acting on the surfaces. Reduce the contact between the surfaces.
Does sandpaper reduce friction?
As the sandpaper got to a certain roughness the grains of sand where larger which decreased the over all contact area and reduced the friction. The grains are larger so there will be fewer contact points.
