Difference Between

Scalar Quantity vs Vector Quantity Math and physics are two subject invented by us to describe various phenomenon around us. This fits perfectly upon quantities that are measured using math and physics. Scalar and vector are classification of quantities in physics. There are some quantities that have only one... 

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... 

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 concept... 

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 measure... 

Static vs Dynamic Electricity We all know about electricity as we see it functioning in the form of lights, fans, A.C’s, refrigerators and many other appliances. It is a kind of energy that has the ability to make appliances work. We cannot see electricity but its effect is seen, heard, smelled and can even... 

Natural vs Artificial Radioactivity Radioactivity has not been invented by man; it has been there, existing in the universe since time immemorial. But it was a chance discovery by Henry Becquerel in 1896 that the world came to know about it. Radioactivity was finally explained by Marie Curie in 1898 who also... 

Stones vs Pounds Stone and pound are units of measurement of weight in the imperial system. Despite the world switching over to the metric system where kilogram is the accepted unit of weight, US and UK still adhere to the imperial system. Interestingly, whereas stone is used to describe the weight of a person in... 

Pounds vs Kilos Since the adoption of the SI system in 1959, the world has moved over to kilogram as the unit of measurement of weight. However, there are countries like the US and UK that are still clinging to the imperial system of weights containing pounds and stone. The relation between a pound and a kilogram... 

Pint vs Quart vs Liters If you are from a country other than UK or US, and someone asks you to explain the difference between a pint, a quart and a liter, you would be flummoxed as you are used to the metric system that uses only liter as a unit of measurement of volume. There are differences hard to remember... 

Ounces vs Pounds Ounces and pounds are units of mass used in the imperial system of measurement, but whereas the world has moved over to kilograms after the adoption of the metric system, some countries still stick to this system of measurement which is what confuses many people. Out of the two units, ounce is... 

Mile vs Kilometer (km) Mile and kilometer are units of measurement of length. While kilometer is used in the metric system, mile is a unit of measurement in the imperial system. Despite dominance of metric system worldwide, mile as a unit of length is used in a widespread manner in all parts of the world. Kilometer... 

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... 

Lysosomes vs Ribosomes Lysosomes and Ribosomes are parts of cells that play important roles that are different from each other. While Lysosomes are a mechanism to digest foods in a cell, ribosomes are designed to synthesize proteins. There are more differences that will be talked about in this article. Ribosomes Ribosomes... 

Flagella vs Cilia Cilia and Flagella are tiny structures appended to eukaryotic and prokaryotic cells of organisms. These structures help in locomotion of cells. They are made up of microtubules that are also called basal bodies. There are many similarities in structures and chemistry of flagella and cilia though... 

Limbless Amphibians vs Snakes Frogs and toads straightaway come to our mind when the word amphibian is spoken. No doubt they are the most celebrated species among amphibians, but there is an order of amphibians that we know very little about and which very much resemble like snakes. Yes, I am talking about limbless...
