momentum newtons

When a bullet is fired from a gun, the gases produced in the barrel exerts a tremendous force on the bullet (action force). As a result, the bullet moves forward with a great velocity called the muzzle velocit..

. The SI unit of momentum is (kg x m/s) or kg m/s. From the above expression, we can understand that when two bodies have equal velocities then the heavier body has greater momentum. Similarly, when two bodies have equal mass, the faster body has greater momentum. Now..

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 t..

Applications of Newton's Second Law of Motion - In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will..

Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied forc..

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 changes from the init..

The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applie..

The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applied. For a constant mass system We have already learnt that the rate of change of velocity is called acceleration where k is the constant of proportiona..

Here, F x and F y are two rectangular components of the applied force p x and p y are the two rectangular components of the momentum p. (at any time t) But we know, The quantity (xp y - yp x ) is known as the angular momentum L. So, the rate of change of angular ..

Inertia is the inability of material body to change, by itself, its state of rest or of uniform motion in a straight line. Mass is a measure of inertia Newton's first law of motion: A body continues in its state of rest or of uniform motion along a straight line unless an external..
