1. What is G-Force in Accidents?

Definition: G-force measures the acceleration experienced during an accident relative to Earth's gravity.

Purpose: It helps quantify the impact forces on vehicle occupants during collisions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — G-force (dimensionless)
• \( a \) — Acceleration (m/s²)
• \( g \) — Earth's gravity (9.81 m/s²)

Explanation: The formula compares the accident acceleration to standard gravity, showing how many times greater the force is than normal gravity.

3. Importance of G-Force Calculation

Details: Understanding G-forces helps engineers design safer vehicles and helps medical professionals assess potential injuries.

4. Using the Calculator

Tips: Enter the acceleration in m/s² (positive for deceleration) and gravity (default 9.81 m/s²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a dangerous G-force level?
A: Sustained G-forces above 5G can be dangerous, while brief peaks up to 20-30G may be survivable with proper safety systems.

Q2: How is acceleration measured in accidents?
A: Crash test dummies contain accelerometers that record deceleration during impact.

Q3: What's the difference between positive and negative G-forces?
A: Positive G-forces push you into your seat (deceleration), while negative G-forces pull you out (rapid acceleration).

Q4: Why use Earth's gravity as reference?
A: It provides a familiar baseline since we experience 1G in daily life.

Q5: How do airbags affect G-forces?
A: Airbags increase stopping distance, reducing peak G-forces by spreading deceleration over more time.
