20+ Everyday Examples of Friction Explained for Students
Corey CrossWhat Is Friction?
Friction is a fundamental force that opposes motion when two surfaces come into contact. It plays a vital role in our daily lives, often acting as an unseen helper or an obstacle we need to overcome. Understanding friction is crucial for GCSE and A-Level Physics students as it connects theory to practical applications.
In this blog post, we’ll explore 20+ examples of friction in daily life, explain its types, and provide tips for approaching exam questions effectively.
Types of Friction
Before diving into examples, it’s important to understand the main types of friction:
- Static Friction: Prevents motion between objects at rest.
- Kinetic (or Sliding) Friction: Acts between objects in motion.
- Rolling Friction: Occurs when an object rolls over a surface.
- Fluid Friction: Resistance experienced by objects moving through fluids (like air or water).
Each type of friction has unique characteristics and applications, which we’ll explore through real-world examples.
20+ Daily Life Examples of Friction
Here are practical examples to help you relate friction to your everyday experiences:
Static Friction Examples
- Trying to push a heavy sofa that doesn’t budge initially.
- Writing with a pencil – the graphite sticks due to friction between the pencil and paper.
- Shoes gripping the ground to prevent slipping while standing.
Kinetic (Sliding) Friction Examples
- Sliding a book across a table.
- Rubbing your hands together to generate heat.
- A sled gliding on snow.
Rolling Friction Examples
- Car tyres rolling on a road.
- A ball rolling across the floor.
- Shopping trolley wheels moving over a surface.
Fluid Friction Examples
- An aeroplane flying through the air.
- A swimmer moving against water resistance.
- A parachute slowing down due to air resistance.
Mixed Examples
- Using brakes on a bicycle – combines sliding and rolling friction.
- Opening a window – friction between the frame and the pane.
- Typing on a keyboard – friction between your fingers and the keys.
Table: Comparison of Friction Types
| Type of Friction | Occurs When | Examples |
|---|---|---|
| Static Friction | Objects are stationary. | Pushing a heavy sofa. |
| Kinetic Friction | Objects are sliding. | Sliding a book on a table. |
| Rolling Friction | Objects are rolling. | Car tyres on a road. |
| Fluid Friction | Objects move through a fluid. | A swimmer in water. |
Practice Exercise: Understanding Friction
To test your understanding, try this question:
Question: A person pushes a box, causing it to slide across a wooden floor. Identify the type of friction acting during this motion and explain its effect.

Exam Tips for Friction-Related Questions
- Always identify the type of friction first. Exam questions often focus on the distinction between static, kinetic, rolling, or fluid friction.
- Use diagrams to illustrate forces acting on objects. Free-body diagrams are particularly effective.
- Relate friction to real-world examples, as this demonstrates practical understanding.
- If calculations are required, remember the formula: Frictional Force = Coefficient of Friction × Normal Force. You may need this in A-Level Physics.

Key Takeaway
Friction is more than a theoretical concept—it’s a force that shapes our everyday experiences. By understanding its types and applications, you’ll be better equipped to tackle questions in GCSE and A-Level Physics.
