WebNov 5, 2024 · In order to simplify the SI unit system, a fundamental (base) set of dimensions was chosen and the SI units were defined for those dimensions. Any other dimension can always be re-expressed in terms of the base dimensions shown in Table 2.2.1 and its units in terms of the corresponding combination of the base SI units. WebThe force which acts on a body for a small duration of time, but produces a significant change in its momentum, is called the Impulse of force. As the impulse of force is the measure of change in momentum, therefore, its units are the same as that of momentum. In the SI system, its unit is newton-second (Ns) or kg m/s. Suggest Corrections.
