Velocity and Acceleration

Vedclass · Answer

(A) Let the position vector of a particle be $\vec{r}(t)$.$1$. The first differentiation of the position vector with respect to time $t$ gives the velocity vector:$\vec{v} = \frac{d\vec{r}}{dt}$$2$. The second differentiation of the position vector with respect to time $t$ (or the first differentiation of velocity) gives the acceleration vector:$\vec{a} = \frac{d\vec{v}}{dt} = \frac{d^2\vec{r}}{dt^2}$Therefore,the first differentiation gives velocity and the second differentiation gives acceleration.

Which physical quantity can be found by first differentiation and second differentiation of position vector?
