Dementional formula of velocity
Answers
Answer:
Velocity, as used in physics, is a vector consisting on speed as the magnitude (or size) and an orientation (direction). Velocity is the ratio of the change in position with respect to time.
The change in position may be called displacement by some and may have other terms. To avoid confusion, we will stick with change in position, which position is defined as follows:
Given a reference point, position is the vector from that point to a given place. This vector maybe 2-D or 3-D, according to the problem to be solved. Thus, a change in position would be a change of place, from an initial to a final place.
Velocity is then the change in position per unit time, as described in other answers to this question.
This gives rise to two complementary definitions which, by the way, they apply to all measurements expressed as ratios:
Average velocity: it is the net change of position during said time interval. It is a vector, with its magnitude being the net position change divided by the time interval.
Instant velocity: it is the ration of net change in position per time interval at a particular time, as the time interval becomes indefinitely smaller and smaller. This is more like the Newtonian definition of derivative of position with respect to time.
Believe it or not, average velocity, speed or other averages are pretty powerful in solving kinematic Physics problems, specially those related to UAM (Uniform Accelerated Motion)
