How Physics Helps in Everyday life with Examples

Physics Helps in Everyday

Physics is essential in our daily lives; in whatever we do, there is physics. We use physics in our daily activities and simple functions such as watching, cutting, and opening and closing things. In this world, many exciting events occur.

These events are around us, and we experience them regularly. Physics plays a significant role in human history and culture. Its advancement has brought many human endeavors such as telecommunications, economic development, and space exploration.

The application of physics concepts in our daily life is numerous, especially now that we live in an era in which technology and science have become part of our everyday life; therefore, physics is a vital subject to study and understand.

Moreover, in the prescientific era, everyday human life was still governed by physics principles. Therefore, Physics is a subject that governs our everyday lives in one way or another. It is a science that helps us understand various natural phenomena.

Application of physics in the field of aviation and space

The study of physics does not only focus on the happenings on the earth; physicists have studied everything that goes to space. We can discover objects such as planets and monitor their movements and locations.  Moreover, scientists have also developed tools and machines that help them learn more about outer space, such as terrestrial telescopes.

Physicists have also analyzed how the radiation reaches the earth’s surface and through which we can understand the layers of the earth’s atmosphere and how energy is transferred through it. In addition, the concept of physics has led to the manufacture and production of space rockets and aircraft.

Application of physics in the field of medicine

Like any other scientific field, medicine also benefits from the concepts of physics; nowadays, many medical technologies and devices depend on physics in their work and application. Some of  the medical application of physics includes:

  1. Radiation oncology – radiation has become the standard treatment method for cancerous cells. Clinicians use radiation to kill cancer cells or to limit their spread to other body organs. Radiation can also be used as adjuvant therapy in addition to chemotherapy and surgery.
  2. Laser surgery relies on the use of light rays; the use of laser is an alternative to the traditional use of scalpels during procedures .it is primarily used in exceptional cases involving soft tissue correction. Some laser surgery options include cosmetic surgery, laser endoscopy, and lithotripsy.
  3. Imaging equipment -imaging devices are essential as it is possible to diagnose diseases with them. Ultrasounds help doctors to capture moving images of specific parts of the body; an x-ray takes the image of the skeleton and helps to rule out any fracture, while magnetic resonance imaging help to capture clear pictures of body parts.

Application of physics in the field of transportation and movement

As stated in Sir newton’s law of motion, the motion of bodies is based on the presence of an external force acting on them .newton stated that there is a relationship between the motion of bodies and the external force.

Engines used in transportation, such as in cars, planes, and trains act as external driving forces that allow them to move and change positions. On the other side, brakes and seat belts work on the contrary by presenting external force opposite to the engine to stop the object’s movement.

Application of physics in the field of energy

Energy exists in many forms, and it can be utilized directly or indirectly by converting it to other forms of energy. Some of these forms of energy include electric energy, kinetic energy, wind energy, and solar energy. The conversion of this energy to different forms requires the use of specific physics principles. Some of the biological applications of energy include:

  1. Solar cells – with the increased need for other sources of fossil fuels, the use of solar cells has become an essential alternative energy source. Solar cells are used to convert solar energy to thermal or electrical energy. Solar cells s are still under development, and research is still ongoing to help suit the requirements of today’s life.
  2. Electricity is the primary energy source– It is one of the most critical direct physical applications in people’s lives .it involves continuous charges s moving inside a conductor and forming an electric current.
  • Wind pumps –wind pumps are devices for moving water using wind power; there are more so used for pumping water in remote areas and scarce area that suffers from scarce water and electric energy .although the pumps are considered inefficient in comparison to today’s electric pumps there are still being used in remote areas.

Application of physics in satellites and communication

Satellites are the most critical applications of astrophysics; they are human-made devices to revolve around the earth or other planets in certain orbits similar to the natural satellites.

The first human-made satellite was launched in October 1957. satellites can also be used for television broadcasting and communication.


The scope of physics is outstanding; it is a science that asks questions about life and seeks answers through experimentation and observations.

Scientists strive to answer fundamental life questions through research and observation; this, in turn, results in discoveries and inventions that enhance our way of life. Nowadays we find the application of physics in different inventions such as alarms mobile phones, video players, computer applications, and many other electronic products.
