The Global Positioning System consists of 24 satellites, that circle the globe once every 12 hours, to provide worldwide position, time and velocity information. GPS makes it possible to precisely identify locations on the earth by measuring distance from the satellites. GPS allows you to record or create locations from places on the earth and … Read more
Spherical Coordinates and Projections,Time Spherical coordinates can be a little challenging to understand at first. Spherical coordinates determine the position of a point in three-dimensional space based on the distance ρ from the origin and two angles θ and ϕ. If one is familiar with polar coordinates, then the angle θ isn’t too difficult to … 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
