Physics: 10 examples of complex theories and equations in everyday life

Physics, often perceived as a realm of complex theories and equations, is an integral part of our everyday lives, shaping the very fabric of the world around us.

From the simplest motions of objects to the most complex phenomena in the universe, the principles of physics underpin much of what we encounter daily. It’s the science that explores the fundamental forces, laws, and interactions governing matter, energy, space, and time.

Whether it’s the way a ball bounces, the light that illuminates our surroundings, or the force that keeps us grounded, physics is a silent yet profound companion, continuously influencing and explaining the mechanics behind everything we experience.

In this context, everyday occurrences reveal a tapestry woven by the threads of physics, enriching our understanding of the world in which we live.

10 Examples of physics in everyday life


Gravity keeps us grounded and governs everything from the way objects fall to Earth to keeping our feet on the ground.


When you walk, friction between your shoes and the ground allows you to move forward without slipping.


Electrical appliances, such as lights, televisions, and computers, all rely on the principles of electricity and magnetism.

For parents looking for an edge.

Your child shouldn’t miss out. LiteracyPlanet is designed to improve English literacy skills for each individual student. So this program is for your child too!

LiteracyPlanet is perfect for 5-15 years olds who are:

  • Homeschooled students, or
  • Students attending mainstream school needing extension work


Boiling water for your morning coffee involves the principles of thermodynamics, as heat energy is transferred to raise the water’s temperature.


Seeing the reflection of your image in a mirror involves the principles of optics and the reflection of light.

Sound waves

When you listen to music or talk on the phone, sound waves are transmitted through the air and converted into signals that your ears interpret.


Newton’s Laws of Motion

When driving a car, the acceleration, deceleration, and turning all adhere to Newton’s laws of motion.


The pressure in your car’s tires affects how it grips the road, and the pressure in a syringe determines how easily medicine can be administered.

Fluid dynamics

Watching water flow in a river or filling up a glass involves the principles of fluid dynamics.


Playing sports like basketball or soccer involves understanding momentum, as the movement of the ball and players follows the laws of conservation of momentum.

These examples showcase how the principles of physics govern and explain numerous phenomena in our daily lives.
