What this calculator does

Velocity is the rate of change of position. Find an average velocity from distance and time, or a final velocity after accelerating uniformly for a known time.

Formula and method

Average v = d ÷ t; final v = u + a t; distance = u t + ½ a t²

Worked example

Calculated by this tool with its default inputs:

Inputs

  • From: Distance and time (average velocity)
  • Distance: 100 m
  • Time: 9.58 s

Results

  • Average velocity: 10.4384 m/s
  • In km/h: 37.578
  • In mph: 23.35
  • Distance covered: 100 m

How to read the results

Results are shown in m/s, km/h and mph.

Assumptions and limitations

  • Constant acceleration assumed in the second mode.

These are educational estimates. Electrical, structural and other safety-critical work must comply with local codes and be designed or checked by a qualified professional.

Questions

Speed vs velocity?

Velocity includes direction; along a straight line they have the same magnitude.
