motion and reference point

The Circle of Reference - The above figure shows a body moving with uniform speed along a circle. Let perpendiculars be drawn from different positions of the body onto any diameter, say the vertical diame..

The maximum displacement of the particle executing SHM from the equilibrium position is known as the amplitude. It will be equal to the radius of the circle of reference. Therefore, the total range of motion is 2..

Rest and motion are relative terms. A person sitting in a moving car is at rest with respect to his or her fellow passengers, but is in motion with respect to other objects or people on the road. Moreover, it is not possible to define 'absolute rest' or 'absolute motion..

Imagine you are travelling in a moving train. Do you observe any change in your position with respect to your co-passengers? Is there any change of scene you view through the window? The change of scene indicates that the train is moving. That is, an object is said to be in motion if it c..

Summary - Motion: Whenever a body changes its position continuously with respect to the position of other bodies around it then it is said to be in motion. Rest: An object which does not change its position with respect to its surroundings is said to be at rest. Distance: It is the a..

Introduction - The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mass. During the seventeenth century Newton develope..

In translatory motion the particle moves from one point in space to another. This motion may be along a straight line or along a curved path. The motion along a straight line is called rectilinear motion..

In vibratory motion the particles move to and fro about a fixed point. Simple pendu..
