motions

In the example discussed under the topic uniform and non-uniform motion we have classified motion along circular track as an example of non-uniform motion. Let us now see why circular motion is considered as non-uniform motion. The figure shows an a..

Motion and Rest - 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..

The first law of motion and inertia also applies to objects in motion. For example, When you pedal a bicycle, you accelerate to make the bicycle move forward. Because the forces acting on the bicycle are balanced, the bicycle and the rider keep moving at the same speed and ..

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 act..

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..

Graphical Derivation of First Equation Consider an object moving with a uniform velocity u in a straight line. Let it be given a uniform acceleration a at time t = 0 when its initial velocity is u. As a result of the acceleration, its velocity increases to v (final velocity) in time t and S is..

Whenever we push or pull an object, we do so by means of a force. Force is an interaction between two bodies which causes acceleration, or simply, motion..

Equations of Motion - The variable quantities in a uniformly accelerated rectilinear motion are time, speed, distance covered and acceleration. Simple relations exist between these quantities. These relations are expressed in terms of equations called equations of motion..
