    What is the change in momentum of an object if a force equal to 'Z' newtons is applied on it for 3 seconds?

  • Question 2
    1 / -0

    What amount of force is applied on a body of mass `m` whose velocity changes from `u` to `3u` in 1 second?

  • Question 3
    1 / -0

    The flying of birds is a consequence of Newton's

  • Question 4
    1 / -0

    According to Newton's Third Law of Motion, action and reaction always act on

  • Question 5
    1 / -0

    Two bodies A and B collide. No external force acts on the bodies during collision. What is the ratio of the masses of body A and body B, if the velocities of the bodies before and after the collision are as given in the table below ? 

    Velocities before collision

    Velocities after collision
    uA = + 5 m/s

    uB = 0

    		 vA = + 2 m/s

    vB = + 4 m/s

  • Question 6
    1 / -0

    Two objects, each of mass 3 kg are moving with the same velocity of 6 m/s in the same straight line but in opposite directions. They collide and stick together. What is the velocity of combined objects after the collision?

  • Question 7
    1 / -0
