Dimensions of second law of motion |
|
Answer» F=ma The MATHEMATICAL equation of Newton's 2ND law. Where m is mass of the object and a is the acceleration. Acceleration, a=v(velocity)/t(time),its S.I. unit is m(metre)/s(second)^2 Where v=s(displacement)/t(time),its S.I.unit is m/s. Displacement is defined to be the change in POSITION of an object. It can be defined mathematically with the following equation. ∆x=xf-xi ∆x-Displacement xf-final position of the body xi-initial position of the body Displacement's S.I. unit is metre(m) ,which is a dimension. Displacement is a vector QUANTITY. |
