As we discussed in our previous post about Newton law’s. We have also seen some of the important examples but here we will talk about the main topic that is friction force.
In this article, we will explore 20 examples of friction in our daily life with simple explanations that are easy to understand.
We all well known about the term friction. Below are the deep discussion on examples of friction.

What are 10 examples of reducing friction?
Here are 10 examples of reducing friction in daily life and various applications:
- Using lubricants (oil or grease)
Applying oil or grease between moving parts of machines reduces friction and prevents wear and tear. - Polishing surfaces
Smoother surfaces produce less friction, so polishing metal or wooden surfaces can help objects slide more easily. - Using ball bearings
Ball bearings reduce friction in machines by converting sliding friction into rolling friction, which is much lower. - Applying powder (like talcum powder)
In activities like gymnastics or weightlifting, applying powder reduces friction between the skin and surfaces. - Using air cushions
Devices like hovercrafts use air cushions to reduce friction between the vehicle and the surface, allowing smooth movement. - Switching to streamlined designs
Vehicles like cars and airplanes are designed to be aerodynamic, reducing air resistance (a form of fluid friction). - Using wheels
Rolling friction is less than sliding friction. Using wheels or rollers under heavy objects makes it easier to move them. - Using non-stick coatings
Non-stick cookware reduces friction between the food and the pan surface, making cooking and cleaning easier. - Magnetic levitation (Maglev trains)
These trains use magnets to float above the tracks, eliminating friction entirely for faster, smoother travel. - Adding water or other liquids
Pouring water between two surfaces (like a slip-and-slide) can reduce friction and make sliding easier.
What are the 10 examples of increasing friction?
- Walking on a rough road or walking on ice.
- Holding a pencil or pen.
- Opening a jar or bottle.
- Brushing your teeth.
- Using brakes in a car or bicycle.
- Playing sports such as baseball or football.
- Typing on a keyboard.
- Using tools such as a hammer or screwdriver.
- Writing on a chalkboard or whiteboard.
- Using zipper.
Friction has many practical applications and can be used to our advantage. For example, friction is used to make car brakes work, to keep a pencil from slipping while we write, and to keep a building from sliding down a hill. However, too much friction can cause wear and tear on machinery and make it harder to move objects. To overcome friction, lubricants such as oil or grease can be used.
In summary, friction is a force that opposes motion between two surfaces, it can be helpful or harmful depending on the context and application, and it has many practical application in our daily life.
Friction is the force that opposes motion between two surfaces that are in contact. It is a force that acts in the opposite direction of the motion of the object and can be either helpful or harmful.
Friction is an important concept in physics and engineering, as it affects motion and energy in many ways. It is responsible for the resistance encountered when attempting to start or stop motion, and also affects the stability and performance of moving parts in machinery.
Friction can be classified into two types: static and kinetic friction. Static friction is the force that oppose motion between two surfaces that are not moving relative to each other, while kinetic friction is the force that oppose motion between two surfaces that are in motion relative to each other.
The coefficient of friction is a number that represents the ratio of the force of friction to the force pressing the two surfaces together.
1. Walking on a rough road or walking on ice.
Walking on a rough road or walking on ice. In both cases, friction between your shoe and the surface you are walking on makes it possible for you to walk without slipping.
If the road or ground is rough, there is more friction between the shoe and the surface, which makes it easier to walk. On the other hand, if the surface is slippery like ice, the friction between the shoe and the surface is much less, making it more difficult to walk.
2. Holding a pencil or pen.
Holding a pencil or pen. The friction between your fingers and the pencil or pen allows you to hold it without it slipping out of your hand. The force of friction acts against the motion of the pencil or pen moving out of your hand.
3. Opening a jar or bottle
Opening a jar or bottle. When you twist off the lid of a jar or bottle, you are using friction to your advantage. The friction between the lid and the jar or bottle holds the lid in place, and you have to overcome this force of friction in order to open the jar or bottle.
4. Brushing your teeth.
Brushing your teeth. Friction is also the reason why a toothbrush bristles can scrub the surface of your teeth clean. The bristles of the toothbrush, which are rough, create a strong force of friction against the surface of your teeth, which helps to remove plaque and food debris.
5. Using brakes in a car or bicycle
Using brakes in a car or bicycle. When you press the brake pedal or the brake lever on a car or bicycle, the friction between the brake pads or brake shoes and the wheels slows the vehicle down by applying a force in the opposite direction of the motion.
6. Playing sports such as baseball or football
Playing sports such as baseball or football. Friction affects the way that the ball behaves in different sports. In baseball, the rough surface of the baseball makes it possible for a pitcher to throw a curveball by creating more friction on one side of the ball than the other. In football, the friction between the ball and the grass makes it possible for a kicker to make a field goal by keeping the ball steady on the ground.
7. Typing on a keyboard
Typing on a keyboard. When you press a key on a keyboard, the friction between the key and the key’s mechanical switch makes it possible for you to type. The force of friction holds the key in place and prevents it from slipping out of your finger’s grasp.
8. Using tools such as a hammer
Using tools such as a hammer or screwdriver. Friction is what allows you to use a hammer or screwdriver to drive nails or screws into a surface. The force of friction between the hammer or screwdriver and the surface you are working on prevents the tool from slipping out of your hand.
9. Writing on a chalkboard or whiteboard
Writing on a chalkboard or whiteboard. The friction between the chalk or marker and the surface of the chalkboard or whiteboard makes it possible for you to write or draw.
Friction is a force that opposes the motion of an object when it comes into contact with another surface. It plays a vital role in our daily lives, helping us perform tasks more efficiently. Without friction, walking, writing, or even driving would be impossible.
What is Friction?
Friction is a resisting force that occurs when two surfaces come in contact and try to move against each other. Depending on the surface type, friction can be high (like rubbing sandpaper) or low (like sliding on ice).
There are four main types of friction:
- Static friction (when objects are not moving)
- Sliding friction (when an object slides over another)
- Rolling friction (when an object rolls over a surface)
- Fluid friction (when objects move through liquids or gases)

Importance of Friction in Daily Life
Friction is essential for many tasks in our daily routines. Here’s why it’s important:
- It allows us to walk, drive, and hold things firmly.
- It helps generate heat in situations like rubbing hands together.
- It slows down or stops moving objects, as seen in brakes or tires.
However, friction isn’t always helpful. In machines, it can cause wear and tear, requiring lubrication to reduce the effect.
