\(\large{ U }\) = magnitude of the velocity (whose dimension is length/time) | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
\(\large{ \Delta x }\) = distance between any two consecative points | \(\large{ ft }\) | \(\large{ m}\) |
\(\large{ \Delta t }\) = time interval | \(\large{ sec}\) | \(\large{ s}\) |
