   Impulse
   Definition (advanced level) The impulse acting on a body (usually during a collision) is equal to the change in momentum of the body.<br /> A constant force F acting for a time t causes an impulse I=Ft.<br /> A variable force F causes an impulse ∫ F dt . <br /> Impulse has dimensions MLT - 1 and SI unit Ns, Newton seconds.

    Impulse
    In classical mechanics, an `impulse` is defined as the integral of a force with` respect` to time: :mathbf = int mathbf, dt where : `dt` is an infinitesimal amount of time. A simple derivation using Newton's second law yields: :mathbf = int frac{dmathbf}, dt :mathbf = int dmathbf :mathbf = Delta mathbf This is often called the `impulse-momentum theorem`. As a result, an impulse may also be regarded as the change in moment...
