graph between physical quantities

Graphs are visual representations of the relationship existing between two variables, one of which is an independent variable and other is a dependent variable. One can calculate many physical quantities by calculating the slope of the graphs. Any inaccuracy..

. Can you tell where each of them would be after say 20 seconds? P and Q can move in any direction. To locate the exact position of P and Q we require their direction of motion als..

. Speed is scalar quantity. SI unit of speed is m/s. Instantaneous speed: It is the speed which the body possesses at a particular instant of time. The speed of a moving object can be determined by calculating the slope of the S-t graph. The S-t graph tells us about th..

Position-time graph for uniform motion - The rate of change of position of a particle in a particular direction gives the velocity of the particle. It may also be defined as the time rate of change of displacement of a particle. Velocity is a vector quantity. A motion is said to..

The condition in which a particular material exists is described by physical quantities such as pressure, volume, temperature and amount of substance. For example, a tank of oxygen in a welding outfit has a pressure gauge and a label stating its volume. We could add a thermomete..

Results and observations of scientific experiments should be properly recorded under headed columns and numbered rows. The headings must include the units in which each quantity is measured. Graphs are very helpful in comparing measurements. The general rule in plotting the ..

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..

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..
