The physics of everyday life

Physics is often thought of as a difficult subject filled with formulas and complicated theories. But, at its heart, the subject, in simple terms, explains how the world around us works. Many ordinary experiences can be understood through simple ideas from physics. 

Take, for instance, walking. When we walk, our feet push against the ground, and the ground pushes back with equal force, helping us move forward. This interaction between forces is what allows us to walk, run, or even jump. Without it, movement would be impossible.

Another everyday example of physics is gravity; something that we learn very learn in our lives. If you drop a pen, it falls to the ground instead of floating in the air. This happens because the Earth pulls objects toward itself. Gravity is also what keeps the Moon orbiting around the Earth and prevents us from drifting away into space.

Physics also explains how we ride bicycles or drive cars. When a bicycle moves forward, the friction between the tyres and the road helps the wheels grip the surface. Without friction, the tyres would simply slip, making it difficult to move or stop safely. The same principle helps vehicles maintain control on the road.

Even something as enjoyable as playing sports involves physics. When a cricket ball is thrown, or a basketball is shot toward the hoop, the direction, speed, and angle determine where the ball will go. Players may not think about physics while playing, but they are constantly applying its principles through practice and instinct.  

Another fascinating part of daily life explained by physics is light and colour. The reason we see different colours around us is that light reflects off objects and enters our eyes. Rainbows, for example, appear when sunlight passes through raindrops and splits into different colours.

Physics also plays a major role in the technology we use every day. Smartphones, computers, televisions, and even Wi-Fi rely on ideas related to electricity, waves, and energy. These discoveries have made communication faster and easier than ever before.

When we begin to observe, it becomes clear that physics is not limited to laboratories or textbooks. It is present in the way leaves fall from trees, how swings move in playgrounds, and how aeroplanes stay in the sky. 

“Physics is often seen as equations in textbooks or experiments in a lab, but in reality, it quietly shapes almost every moment of our daily lives. From the way a ball bounces to the glow of a lamp, physics explains the forces, energies, and motions that make life possible. The world we experience every day is a living laboratory of natural laws waiting to be noticed.” shares Ms Preeti Gaur, PGT Physics, Apeejay School, Pitampura 

Ms Gaur allso added: “As Albert Einstein once said, “Look deep into nature, and then you will understand everything better.” Likewise, Isaac Newton reminded us, “What we know is a drop, what we don’t know is an ocean.” Observing the world with curiosity reveals that physics is not distant or abstract—it is everywhere, quietly orchestrating the rhythm of everyday life.

From the light that brightens our mornings to the electricity that powers our evenings, every small act—walking, cooking, listening, or playing—is a living testament to the laws of physics. The more we notice, the more magical our everyday world becomes.”

In many ways, physics helps us see the hidden rules of nature. By understanding these simple principles, we can realise that the world around us is not random, as it follows patterns that science helps us understand.
