Do the advantages outweigh the disadvantages topics?
Tips for Outweigh Essay Questions
- you can use the word “outweigh” in your introduction if you want.
- or you can simply explain if there are more advantages or disadvantages in your opinion.
- avoid formulaic statements for your thesis statement – this means don’t use a memorised phrase.
What are 3 advantages of friction?
Advantages of friction:
- Friction enables us to walk freely.
- It helps to support ladder against wall.
- It becomes possible to transfer one form of energy to another.
- Objects can be piled up without slipping.
- Breaks of vehicles work due to friction.
- It always resists the motion, so extra energy is required to overcome it.
What are the advantages of friction in our daily life?
Advantages of friction :
- Friction helps us to walk on the ground.
- We are able to write on the board due to friction.
- Friction helps in stopping a car by applying the brakes.
- It helps in the generation of heat when we rub our hands.
- Asteroids are burnt in the atmosphere before reaching Earth due to friction.
What are the uses of friction in our daily life?
10 examples of friction in our daily life
- Driving of a a vehicle on a surface.
- Applying brakes to stop a moving vehicle.
- Skating.
- Walking on the road.
- Writing on notebook/ blackboard.
- Flying of aeroplanes.
- Drilling a nail into wall.
- Sliding on a garden slide.
How is friction a problem?
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 is friction not useful for?
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 are 3 types of friction?
The reason we are able to control cars at all is because of friction between the car’s tires and the road: more accurately, because there are three kinds of friction: rolling friction, starting friction, and sliding friction.
What is friction explain with example?
Friction acts as a resisting force which is generated , when two solid surfaces slide against one another. Examples :- <> For walking , there is a friction between our shoes / feet . <>There is a friction between the tires of a vehicle and between the road.
What are the 2 types of friction?
There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren’t moving relative to each other, while kinetic friction acts between objects in motion.
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.
Can water reduce friction?
Water can either increase or decrease the friction between two surfaces. Water reduces the friction between rubber tires and road pavements. That’s why drivers have to be extra careful not to skid when roads are wet. Water can increase the friction between your fingers and a sheet of plastic.
Can we reduce friction to zero?
Friction can be reduced to a great extent by polishing surfaces or by using a large amount of lubricants such as oil, water, or grease but we cannot reduce friction to zero.
How is friction due to air reduced?
Explanation: Friction due to air is considerably reduced by streamlining the shape pf the body moving through air. For example, jets have a streamline shape. The force between the tyres and the road is small to provide the necessary centripetal force.
How we can increase friction?
There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction between the tyre and the road.
What is fluid friction How is it reduced?
The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water . For example: 1)Cars are built with streamlined body shape to reduce air resistance or drag caused by a air.
What is friction due to fluid called?
Friction due to fluids is called drag.
What is called fluid friction?
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.
What are the factors that fluid friction depends on?
The frictional force on an object in a fluid depends on its speed with respect to the fluid. The frictional force also depends on the shape of the object and the nature of the fluid.
What is the basic cause of friction?
Causes of Friction: Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
Why can we never reduce friction to zero?
No , we cannot have zero friction surfaces . Even if we use a lot of lubricants , the friction will be reduced but can never be reduced to zero because every surface will still have minor irregularities in them.
What produces friction?
Friction is produced due to the irregularities between surfaces. Thus, when these surfaces rub against each other they produce heat. And the heat gets trapped in these irregularities.
