Last Updated on December 22, 2022 by Sherouk Badr Shehata One of the most famous and revolutionary scientific theories of the 20th century is Einstein’s theory of relativity. It was proposed by the German-born physicist, Albert Einstein, in 1905 and has since then been accepted as a fundamental theory of…

Last Updated on December 20, 2022 by Nourhan Essam Have you ever thought about how we can get fresh water from sea water? Or how can we get the skim milk? Or how is blood separated into its four components in hospitals and blood banks? Sand and water/ Cereal and…

Last Updated on December 10, 2022 by Sherouk Badr Shehata Have you ever dreamed of defying gravity? That dream can now become a reality with the free-fall experiment. This experiment is a great way to learn about the principles of gravity, acceleration, and the conservation of energy. It is also…

Last Updated on November 15, 2022 by Sara Assem Have you ever wondered how physicists create free-body diagrams? What about economists or biologists? All of these professionals use specific symbols to chart the motion of an object. The importance and virality of free-body diagrams (FBD) in physics are beyond description.…

Last Updated on November 15, 2022 by Sara Assem A true wonder of humanity’s creative mind and engineering is the spring! With its many different forms and specific functions—the coil spring, the compression spring, the extension spring, the torsion spring, and more—our mankind was offered the chance to fabricate and…

Last Updated on November 15, 2022 by Mostafa Pressure is an intrinsic property of matter. You can exert pressure on a solid, a liquid, or on a gas, and so can solids, liquids, and gasses according to the surrounding conditions. A famous example in this context is the cautionary signs…

Last Updated on May 25, 2023 by Sara Assem Bernoulli equation, or the incompressible steady flow energy equation, is considered one of the most well-known equations in physics ( fluid mechanics) and it explains the conservation of mechanical work-energy. The equation was published in 1738 by Daniel Bernoulli (a Swiss…

Last Updated on February 25, 2025 by Zinab Hasssan “Force” is one of the very essential terms used in physics. Every time and everywhere we—as scientists, or as a public crowd—are about to observe or examine a phenomenon closely, we find that a force is controlling or resulting in that…

Last Updated on April 11, 2023 by Sara Assem The laws of physics are prominent in our everyday life, as they permeate, govern, and fully control every step we take and every move we make. The various applications of Newton’s third law of motion form a good example to recall…

Last Updated on April 11, 2023 by Sara Assem The principle of inertia is one of the fundamental principles in classical physics that are still used today to describe the motion of objects and how they are affected by the applied forces on them. Inertia comes from the Latin word,…
