The Average Velocity calculator computes the velocity (V) based on the change in position (Δx) and the change in time (Δt).

INSTRUCTIONS:  Choose your units for length (e.g. feet or meters) and time (e.g. minutes or days) and enter the following:

• (Δx)  Change in distance
• (Δt)   Change in time

Velocity(V): The calculator computes the velocity (V) in meters per second (m/s).  However this can be automatically converted to numerous other velocity units (e.g. mph) via the pull-down menu.

#### The Math

v = Δx / Δt

where:

In vector notation this can also be represented as the difference between two position vectors separated in time:

|v_"Avg"|  = (|Deltavecr|)/(Deltat) = |vecr_2 - vecr_1| / (t_2 - t_1)
