problems involving elastic and inelastic collisions in one dimension

The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on (1) elasticity and (2) density o..

Case (i) when m 1 = m 2 , i.e., when both the colliding bodies are of the same mass. The velocity of body A after collision, is equal to the velocity of body B before the collision. From equation (v), The velocity of body B after collision, is equ..

Assumptions stated by Classius - All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are different. The gas molecules behave as rigid, elastic and smooth spheres. The size of gas molecules is very less when compared to the interm..

Speed of Sound - The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on (1) elasticity and (2..

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In this chapter..

Kinetic Theory of Gases - The word 'Kinetic' means due to motion. The Kinetic Theory of Gases is based on the idea that gases consist of atoms and molecules moving ceaselessly and randomly with all possible velocities in all directions. Each of these gas particles has certain amount of kinetic ener..

Law of Conservation of Momentum - From Newton's third law of motion we know that whenever a force is applied on a body there will be an equal and opposite reaction. Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of these bodies. In an h..

. i.e., a to and fro motion. A given point in the path is crossed by the body in opposite directions at regular intervals. This is called oscillatory motion. All oscillatory motions are periodic but not all periodic motions are oscillatory. On observing an oscillating system, like a loaded spring, ..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the transition state. The..
