Calculation Result
The impact g-force is:
0 g
This means the object experienced a force 0 times the force of Earth’s gravity.
Formula Used:
g-force = (velocity²) / (stopping distance × 9.80665)
Where:
- velocity is in meters per second (m/s)
- stopping distance is in meters (m)
- 9.80665 m/s² is the acceleration due to gravity
Frequently Asked Questions
What is g-force in an impact?
G-force measures the acceleration experienced during an impact relative to Earth’s gravity (1g = 9.8 m/s²). Higher g-forces indicate more severe impacts.
How is impact g-force calculated?
Impact g-force is calculated using the formula: g-force = (velocity²) / (stopping distance × 9.80665). This accounts for how quickly an object decelerates.
What’s a dangerous g-force level?
Sustained g-forces above 5g can be dangerous for humans. Brief impacts can be survived at higher levels (e.g., 50g for milliseconds), but may still cause injury.
