Integrating the above equation and applying the limits which are at s = 0, initial velocity = u after a distance s has been covered, the final velocity = ..

Velocity of Sound in Gases (Newton's Formula) - We know that the properties of a medium that govern the propagation of a mechanical wave are: a restoring force an inertial mass The restoring force acting on the particles of the medium is intimately connected to the approximate elastic mod..

u = initial velocity v = final velocity a = uniform acceleration s = distance covered We know that Integrating the above equation and applying the limits which are at s = 0, initial velocity = u after a distance s has been covered, th..

Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity changes from the initi..

All of us know that a car moving on road does not have a uniform velocity. Either the speed or the direction changes. Whenever a vehicle is speeding i.e., when the speed is increased we say that the vehicle is accelerating. To get an idea of acceleration, let us study the change in v..

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) i..

Newton's Second Law of Motion - Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity c..

according to the definition Cross-multiplying, we have, v (t 2 ) - v (t 1 ) = a (t 2 - t 1 ) v (t 2 ) = v (t 1 ) + a (t 2 - t 1 ) If the motion is considered from t = 0, then the corresponding velocity v(0) at t = 0 is called the initial velocity and the velocity..

As the initial velocity, final velocity, distance travelled, acceleration and time are related and are expressed as equations of motion in linear motion; one can derive equations for rotational motion also. If w 0 is the initial angular velocit..

Law of Conservation of Momentum - Let two particles A and B collide with each other. Let be the initial and final velocities of particle 1 and similarly, for particle 2. Let the two particles be in contact for a time t. Change in momentum of A and B are During the coll..
