physical quantities mass

Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the objec..

Mass - Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the object. If you push a book, it moves faster than if you pus..

There are 7 physical quantities viz., Length, mass, time, temperature, electric current, luminous intensity and amount of substance. Length, mass and time are called fundamental physical quantities..

Mass and weight are commonly mistaken as the same, but they are two different quantities. Now let us try to find out the differences between th..

is defined as the amount of matter contained in it. The SI unit of mass is kilogram (kg). Mass is a scalar quantity. The amount of matter contained in a body does not change with time or from place to place i.e., mass of a body remains the same throughou..

The principle of homogeneity of dimensional equation is used to derive a relation between various physical quantities. To derive a physical relation, the dependent factors of a given physical quantity is found. Assuming its dimensions in terms of th..

According to Newton's second law of motion, F = ma If a constant force 'F' is applied to a body for a very long interval of time, the velocity of the body will go on increasing due to the acceleration produced in the body. This velocity may become equal to, or even exceed the velocity of light, ass..

The value of a physical quantity can be obtained in some other system, when its value in one system is given using the method of dimensional analysis. Measure of a physical quantity is given by X = nu, u - size of unit, n - numerical value of physical..

0 and 'c' are constants, c 2 . 2m dm - m 2 . 2v dv - v 2 . 2m dm = 0 c 2 dm = mv . dv + v 2 dm = dK [from equation (i)] dK = dm . c 2 If particle is accelerated from rest to a velocity v, let its mass m 0 increase to m. K = (m - m 0 ) c 2 K + m 0 c 2 = mc 2 Here, the ..

The units of fundamental physical quantities are called fundamental units. They are length, mass and time. These units can neither be derived from one another nor can be resolved into any other units. They are independent of one anothe..
