In this post, we will study the Difference between fundamental quantity and derived quantity. We will also analyze a few physical quantities to find out whether those are fundamental or derived quantities. Difference between fundamental quantity and derived quantity – with examples Length, Mass, and Time – Each of these 3 physical quantities doesn’t depend […]
Very often while solving numerical problems of physics we need to take the help of Conversions of Volume units – litre to m3 or litre to cm3 or vice versa. (liter and litre are considered the same). As we try to convert from one unit to the other then the conversion factors come as useful […]
Km/h to m/s or km/hr to m/s conversion: To convert km/hr value to m/s value just multiply the km/hr value with 5/18 and get the value in m/s. As example, 36 km/hr = 36 * (5/18) m/s = 10 m/s. So, for this unit conversion from kilometer/hour to meter/second, you need to remember the conversion […]
While studying the chapter on gas laws you must have come across the term ‘mole’ or ‘mol‘. You may have seen gram-mol as well in that chapter. I find many students confused with mole (or mol) and molecule. Here we will discuss and explain the concept of mole or mol with some examples. 1> In […]
Density is the mass per unit volume. The unit of density in SI is Kg/meter3. The relative density or specific gravity of a substance is the ratio of its own density and the density of water. It’s a number only without any unit. What is the difference between density and relative density? Density is the […]
