Last Updated on October 19, 2025 by Muhamed Elmesery 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. Free-body diagrams emerged since Newton’s laws of motion stretched out …

Last Updated on October 19, 2025 by Muhamed Elmesery 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 invent many more useful objects. This man-made revolution of tools …

Last Updated on October 19, 2025 by Muhamed Elmesery 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 on your perfume bottle, saying “the bottle should not …

Last Updated on August 22, 2025 by Muhamed Elmesery 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 physicist) to help us understand fluid flow. Daniel Bernoulli was …

Last Updated on August 22, 2025 by Muhamed Elmesery “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 phenomenon. Forces are instinctively different from each other; they have …
