5 Examples of Physics in Everyday Life

On this “Living Planet” that we call Earth, there are lots of interesting events that take place. These events are around us, which we see or do or experience regularly. At some point in time, your curiosity would have pushed you to ask questions about what’s going on? How does that happen? Well, leaving miracles apart, the answer to all these questions is “Physics.” In fact, Physics governs our everyday lives in one way or the other. Let’s have five examples of Physics in everyday life

1.Car Seat-Belts

Have you ever noticed that on which principle does your car seat-belt work? Well, it’s Physics. When you tighten your car seat-belt, it works on the concept of “Inertia.” Inertia is unwillingness or laziness of a body to change its state of rest or motion. In case of a car collision, your seat-belt helps prevent your body from moving in a forward direction; as your body resists being stopped because of inertia of motion.

2.Camera Lens

The phenomenon of “Selfie” has engulfed people of every age groups. You entertain yourself by clicking photos. The Lens used in a camera works on the principle of Optics. The set of convex lenses provide the camera with an image outside of the camera.

3.Cell Phones

Cellphones have become like Oxygen gas in modern social life. Hardly, anyone would have been untouched by the effects of a cell phone. Whether conveying any urgent message or doing incessant gossips, cellphones are everywhere. But do you know how does a cell phone work? It works on the principle of electricity and the electromagnetic spectrum, undulating patterns of electricity and magnetism.

4.Batteries

Whether in cellphones, cars, torches, toys, or any other appliance, batteries act as saviors of electricity. Batteries work on the principle of capacitance. Since the late 18th century, capacitors have been used to store electrical energy. Benjamin Franklin was the first to coin the phrase “battery” for a series of capacitors in an energy store application.

5.Doppler Radar

To check the over-speeding vehicles, police often use Doppler Radars. Doppler Radars work on the principle of Doppler Effect. The Doppler Effect is nothing but a change in the pitch of a sound when the source of the sound is moving relative to the listener. It is because the frequency of the sound wave changes as the source of sound moves closer to or farther from the listener.
