Derived unit of length
WebUnit of length, meter (m): Meter is the SI unit of length and is defined by taking the fixed value of the speed of light in vacuum. It is expressed as m.s -1 . Unit of mass, kilogram (kg): Kilogram is the SI unit of mass and is … WebNov 5, 2024 · We can start by expressing the dimension of acceleration, since we know from its SI units that it must have the dimension of length over time squared. [acceleration] = L T2 Since force has the dimension of mass times acceleration, we have: [force] = [mass] ⋅ [acceleration] = M L T2 and the SI units of force are thus: SI[force] = kg ⋅ m / s2
