Different types of sensory instruments are used to determine the location and orientation of an object. The two most common of these instruments are the accelerometer and the gyroscope. When integrated into a signal device, they produce incredibly...
Researchers revisit the concept of a space elevator with a minor modification. Instead of anchoring the cable on Earth, anchor it on the moon and dangle it toward Earth. This would make lunar and terrestrial gravitational pull cancel each other...
Thermal energy refers to the energy possessed by an object due to the movements of particles within the object. It’s the internal kinetic energy of the object, which comes from the random movements of the object’s molecules and atoms...
Scientists produce an astonishingly loud sound underwater, louder than the sound of a rocket launch. It generated 270 decibels of sound pressure levels and 1GW/m2 of sound intensities. Sound is defined as a longitudinal wave created by compressions...
We need to be more specific when talking about how heavy an element is. There are two possible ways to define the “heaviest” elements – based on their density or atomic mass. The heaviest element in terms of density can be defined...
What happens when you leave a bowl of hot soup on a table? It gets cold after some time due to the loss of heat to the surrounding air. And that’s (transfer of heat) what we call convection. There are three types of heat transfer: radiation...
Most of the modern devices use sensors to monitor and control various physical quantities like pressure, temperatures, humidity, light intensity, direction, etc. One of such sensors, used to measure the acceleration of the devices, is called the...
Ammonia is a colorless gas that is produced from natural sources as well as industrial synthesis. About 175 million tons of ammonia is produced synthetically every year. More than 85% of produced ammonia is used as fertilizers and in household...
In physics, a force can be defined as a push or pull on any object that has mass. It changes the object’s motion. In other words, a force causes an object with mass to change its direction and velocity. Two great physicists Isaac Newton and...
Everything in the Universe — from Earth’s core to farthest galaxies — is made of atoms. It’s a fundamental unit of an element. So far, 118 elements have been identified (all are listed in the periodic table). The word...
Holograms are virtual 3D images generated by the interference of light beams that reflect off real, physical objects Holograms retain the depth, parallax, and other properties of the original object. They are excellently suitable for presenting...
In physics, energy can be defined as the capacity to do work. Just like there are many different ways of doing work, there are also different types of energy. Energy is a quantitative property. As per the law of conservation, energy can neither be...
