Have you ever wondered why bullets travel such a short distance in water, while torpedoes move at an alarming speed? Unlike air, water is a much denser medium which means it requires more energy to move through. This fact is why moving through water is much more challenging than air. In this article, we will …

How LCDs Vary Light Intensity? When it comes to LCDs, it is important to understand how they are able to vary light intensity. In this article, we will explore how exactly this happens and what occurs when an electric field is applied. Understanding TN LCDs For the purposes of this article, we will focus on …

When working with EM theory, the term skin depth is often discussed. Skin depth is a measure of how much an EM wave can penetrate a medium. From this arises the concept of skin effect, which explains the flow of current in a conductor. Most of the current flows over the skin of the conductor …

When it comes to physics, it’s important to understand the difference between speed and velocity. While speed refers to the distance traveled by an object in a given amount of time, velocity includes both the speed and the direction of the object’s movement. Now, the question is whether it’s possible for a particle to have …

If you’re working on a DIY project that involves inserting a metal bar (beam) of square section, , partially into a continuous medium (such as a wall), you may be wondering how the pressure (or force per unit area) is distributed in the contact surfaces between the cantilever beam and the wall when a force …

Introduction When it comes to understanding the behavior of electronic circuits, many people turn to hydraulic analogies. This can be a great way to wrap your head around the sometimes complicated concepts involved in electrical engineering. By comparing the flow of electricity to the flow of water, you can visualize how different components of an …

As windsurfers, we have all experienced the difference in wind force when sailing in different regions, particularly in warmer versus colder weather. Some have even claimed that they have sailed in 40 knots wind on a 30⁰C day with a certain sail size which they would normally use for sailing in 20 knots back home …

Methods of Deliberately Patterning a Thin Film Interference Pattern On Glass Thin film interference patterns are beautiful and fascinating phenomena in physics. They occur when light waves reflect off a thin transparent film and interfere with each other, creating bands of bright and dark fringes. Many natural phenomena, such as oil slicks on water and …

As someone who is taking a course on analytical mechanics, you may be wondering about the practical applications of this field of study. Analytical mechanics involves the use of mathematical tools and principles to study the motion and forces of physical systems, from rigid bodies to fluids. In this article, we will explore some of …
