Introduction
There is certain evidence that some things occur in our lives daily, but have you ever imagined why and how this could happen? For example, a driver applies brakes to slow down a car at a traffic signal, but how does a car stop while brakes are applied? Why do we slip and fall while trying to walk on a wet floor or a banana peel? All of these happen because of friction. These are a few examples, but we face many such types of circumstances in our daily life. In this article, we will help you to find out the answers to such types of questions.
Friction is a force of opposition that one objects or surface experience while moving above another. Friction is a force but not a fundamental force like gravity. The force of friction resists the motions between moving objects or surfaces that are touching. Sometimes friction works for us and sometimes works against us. For example, if we feel cold, we can rub both hands together to create heat. On the contrary, slips on ice, wet floor, banana peel are some of the examples of friction that works against us. Moreover, friction is very functional and increasing and reducing friction is conditional to external factors.
Mainly, there are two factors affecting friction. These two factors are:
In some cases, the frictional force causes a lot of losses. Hence, we can say for a few cases, friction is a necessary evil. For example, fire in the forest is caused due to the friction between tree branches, unnecessary heat produced by friction may lead to energy wastage, and friction also slows down the motion of movement of an object as friction force acts in the opposite direction of motion.
Yes, wheels can reduce friction. Wheels reduce friction by allowing the touching surfaces to move by rolling instead of sliding or dragging over one another. And because of reducing friction, we can use less force on wheels to move the object.
Friction is divided into four types, and all these four frictions are different from one another:
Examples of the application of friction
Various examples of the application of friction are mentioned below:
1. What is friction easy definition?
In simple words, friction can be defined as a resisting force that is generated when two hard surfaces skid against each other.
2. What are the 4 types of friction?
The 4 types of friction are Sliding Friction, Static Friction, Fluid Friction, and Rolling Friction.
3. What causes friction?
Friction is caused when the surface of two objects are touched with one another by joining irregularities.
4. What are 5 examples of friction?
The 5 examples of friction are:
5. What 2 factors affect friction?
The 2 factors that affect friction are:
6. Does speed affect friction?
Yes, speed can affect friction as friction only happens by the interaction of two surfaces. The friction force of an object is higher when acceleration is higher.
Friction is a very important topic from Physics for 11th standard students. To know more about friction and its examples, you can download our MSVgo app. MSVgo is a video library app that explains the core subject with various examples. The interesting examples will help you to know the concept of friction in a more clear way. So, without any delay, download the MSVgo app on your mobile from the play store.
From the above definition and examples of friction, we have clearly understood that, in our daily life, we all have experienced friction. We can walk because of frictional force as friction holds our shoe to the floor while driving car friction between tyres and the roads can stop the car from slipping, etc. For some conditions, friction is good, while for some other conditions, friction can be harmful as we have already discussed above in this article.
