Definitions and ExplanationsWhat is Dielectric Constant? Dielectric constant is a measure or ratio of permittivity of a given dielectric substance to the permittivity of space. Permittivity pertains to the resistance or ability of a specific material to be polarized when forming an electric field. In physics, when the dielectric constant increases, electric flux density also increases. If [...]
What is Diffusion? There are many scientific concepts that we cannot readily relate to because they rarely cross our paths in everyday activity. Actually witnessing them will almost always require putting on a lab coat and going through an intricate process which might eventually not give the desired results. This however is far from the [...]
What is Elastic Deformation? Elastic deformation is a physics term referring to the process an object undergoes where it retains it shape after deformation once pressure is removed. Sometimes also referred to as reversible deformation, linear elastic deformation (linear relationship between stress and strain) is governed by Hooke’s law of elasticity, which states that a [...]
What is Physics? Physics covers a wide range of scientific study and is a complex subject. However, to define the subject – Physics is the scientific method of understanding matter and energy and how they interact with each other. Physics can be considered as the most fundamental of natural sciences. Is there really a need [...]
Understand the Seven Attributes of Mass When you talk about matter mass will always be a part of the subject. What is mass? In simple terms mass is the amount of matter contained in a particle or an object. Generally, mass is always mistaken to be the same as weight. Actually, they are different for [...]
If you needed to describe matter in one word, that word would be substance. Matter is anything that has mass and takes up space. As long as there is no vacuum there is matter present. It exists in three main forms which are solid, liquid and gas with unique characteristics in each form. Matter in [...]
Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. It is also the reason why water flows much faster than mercury. There are many other areas where density is applicable and evidenced. Now [...]
Most people will have come across the term volume and most of them relate it to the level of audio output. Though this may be the more common meaning and use of the term in everyday speech, there are other meanings to the word. The meaning of the term is unique in mathematics, IT, publication [...]
Energy can simply be described as the capacity or ability to cause physical change. It is a requirement to achieving anything physically. It does not occur in tangible state but is more of a condition possessed by naturally occurring elements. Energy is measured in joules or ergs and occurs in various forms. A fundamental rule [...]
