Distance between two points Here is how to calculate the distance between two points when you know their coordinates: Let us call the two points A and B We can run lines down from A, and along from B, to make a Right Angled Triangle. And with a little … Read more
Newton’s law of universal Gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravitation Gravitation is the force by which every mass or particle of matter, including … Read more
RELATIVE SPEEED AND TRAIN QUESTIONS Speed has no sense of direction unlike the velocity. Relative speed is the speed of one object as observed from another moving object. Questions on train are the classic examples of relative speed and in all these questions it is assumed that trains move parallel … Read more

Measurement of any physical quantity involves comparison with a certain basic, arbitrarily chosen, internationally accepted reference standard called unit. The result of a measurement of a physical quantity is expressed by a number (or numerical measure) accompanied by a unit. A unit of measurement is a definite magnitude of a quantity, defined and adopted by … Read more
In this module we will deal with basic concepts of time and distance, speed, Average speed, conversion from km/h to m/s and vice versa. This chapter will form the basis of further concept of relative speed which is used in train and boat problems. Important Formulas Speed=Distance/Time Distance=Speed×Time Time=Distance/Speed To convert Kilometers per Hour(km/hr) … Read more
