Earth vs Neutral Earthling and neutral wire are safety mechanisms for the protection of a building and its occupants should there be a fault in electrical appliances, power chords or plugs that are inserted into electric circuits. There are many similarities in an earth wire and a neutral wire; so much so that many times […]

Amps vs Volts Amperes (amps) and volts are the basic concepts that one learns when studying electricity in physics. While current in electricity is measured in amps, voltage describes potential difference across terminals or bodies. There is another physical property of substances that allow flow of electricity through them and is known as resistance (r). […]

Propeller vs Impeller For those who have studied motion, especially that of different types of fans, there is no confusion between the terms propeller and impeller but ask those who think they have heard these two terms but haven’t studied them and you will get all sorts of answers. Part of the confusion is also […]

Kinematics vs Dynamics Physics is the study of matter, their energy and their interaction. Physics is also the study of motion of objects. This study is also known as dynamics, a word that is derived from a Greek word dunamis that means power. Now study of motion is not possible without knowing the causes of […]

Acceleration vs Retardation The concept of acceleration is an important one when it comes to study of moving bodies. Acceleration refers to the rate in change of velocity of a moving body. If a body is moving at a constant velocity, there is no change and hence it has no acceleration. You can understand the […]

Absolute Pressure vs Gauge Pressure Pressure is an important concept in physics and finds scores of industrial and daily life. It is defined as force per unit area when it is applied in a direction perpendicular to the surface of the body on which it is applied. But what we measure with devices designed to […]

Pyranometer vs Pyrheliometer Pyranometer and Pyrheliometer are two instruments that are used to measure solar irradiance. Both are similar in their objective though have differences in their design and working principle. This article attempts to highlight these differences. Renewable sources of energy have become very important these days considering fast depletion of fossil fuels and […]

Static Energy vs Kinetic Energy Energy is defined as our ability to do work. Energy takes many forms and it can neither be created nor destroyed. The total energy of the universe remains constant and just changes itself into different forms such as light energy, heat energy, fuel energy, wave energy, sound energy, chemical energy […]

Sublimation vs Evaporation There are processes through which matter changes its form, and in normal circumstances a matter in solid state first transforms into liquefied state and then transforms into gaseous state. However, there are substances that get converted into vapor state without changing into a liquid form from their solid states. This is known […]
