G-Force Calculator

Your details

Choose the physical scenario you want to analyse. Each mode shows only the relevant inputs.
Unit for both start and end speeds.
Speed at the start of the event (use 0 for a standing start).
m/s
Speed at the end of the event. Enter a lower value than start speed to model braking.
m/s
Time over which the speed change occurs, in seconds.

0.708 g of acceleration (6.94 m/s^2)

  • 0.708 g means every kilogram of mass experiences 6.94 newtons of force.
  • This is comparable to a typical car launch or moderate braking event.

Next stepCompare your result against the reference table below to see how it relates to real-world events.
