Question

dimensions of initial velocity.
​

Answer 1

Answer:

Velocity is distance divided by time.

The dimension of distance (length) is L and the dimension of time is T.

${ \sf{contribution \: of \: length \: to \: velocity \: is \: { \sf{ \red{L¹}}}}}$

$\: { \sf{contribution \: of \: time \: to \: velocity \: is \: { \sf{ \red{ {T}^{ - 1} }}}}}$

In velocity there is no mass.

$\: { \sf{contribution \: of \: mass \: to \: velocity \: is \: { \sf{ \red{ {M}^{0} }}}}}$

$\: { \sf{dimensions \: of \: velocity \: is { \red\: {L}^{1} {M}^{0} {T}^{ - 1} }}}$
