Graphical Representation of Motion

Concept of motion and it's graphical representation has always been a jargon and a pain to students of class 9th,10th,11th and 12th, be it RBSE or CBSE. Even for cracking IIT and NEET this concept has to be done well. We at Alchemy Learning always insist on getting the concept right. Distance – Time Graph: When an object is moving with uniform velocity, the slope of graph is always a straight line. In other words, slope of straight line of a distance-time graph shows that object is moving with uniform speed. In the above graph, straight slope line shows that object is moving with uniform velocity. Slope OA shows the speed of the object. Calculation of Speed using distance-time graph: To calculate the SPEED, let take two points A and B on the slope OB. Draw a line parallel to y-axis and another parallel to x-axis from B. Again draw a line parallel to y-axis and another parallel to x-axis from point A. Let, line parallel to x-axis from point B cut

INTRODUCTION OF MOTION

In our blog for the students of 9th,10th,11th,12th, NEET and IIT , this is a post dealing with one of the most complicated and a deemed-to-be very tough topic. We have made it very simple and can be useful for both RBSE and CBSE students INTRODUCTION OF MOTION: In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behavior of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinetics and Dynamics. Kinematics deals with the study of motion without taking into account the cause of motion. Dynamics is concerned with the cause of motion, namely force. Motion: If an object changes its position with respect to its surroundings (reference point) in a given time, the object is said to be in motion. Rest: When an object does not change its position with respect to its surroundings (reference point) in a given time, the object is said to be in rest. Position:
