law of momentum q and a

It is a dynamic property which a body possesses due to the combined effect of mass and velocity. A rolling marble can be stopped more easily than a bowling ball moving at the same velocity. Both objects have inertia of motion, or momentum. However, the bowling ball has more momentum..

If no external force acts on a system of colliding objects, then the total momentum before collision is equal to the total momentum after collision, in the same directio..

The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved and remains unchanged due to reaction forces between the forces of the syste..

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 mo..

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 elastic collision the ini..

From (1) we get, which is the law of conservation of momentum. Generalising to n particles, The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved and remains..

Kepler's second law - Consider a particle A having linear momentum and radius vector with respect to the origin as given in the figure. After a time D t, the particle is at B and the radius vector becomes + D . The velocity of the particle has a radial component v r and an angul..

Let us consider a student seated on a stool that can rotate freely about a vertical axis. The student, who is set into rotation at a modest initial angular speed w i , holds two dumbbells in an outstretched hand. His angular momentum lies along the vertical rotation axis, pointing upwards..

>As is known, EMF is induced in a circuit only when amount of magnetic flux with the circuit changes. As f =BA cos q , therefore, three methods of producing induced EMF are (i) by changing B (ii) by changing A and (iii) by changing q . When a conductor of length l moves with a v..

Conservation of Angular Momentum - We already know two powerful conservation laws, namely, the conservation of energy and the conservation of linear momentum. Let us study another conservation law, namely the law of conservation of angular mome..
