1. What is G-Force in Turns?

Definition: G-force measures the acceleration experienced during a turn, expressed in multiples of Earth's gravity (1G = 9.81 m/s²).

Purpose: This calculation is crucial for vehicle design, roller coasters, aviation, and any scenario involving circular motion.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — G-force (dimensionless, multiples of gravity)
• \( v \) — Velocity (meters/second)
• \( g \) — Acceleration due to gravity (9.81 m/s²)
• \( r \) — Radius of the turn (meters)

Explanation: The formula calculates the centripetal acceleration as a multiple of Earth's gravity.

3. Importance of G-Force Calculation

Details: Understanding G-forces helps design safe turns in roads, tracks, and flight paths, and determines human tolerance limits.

4. Using the Calculator

Tips: Enter velocity in m/s, gravity (default 9.81 m/s²), and turn radius in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical G-force humans can tolerate?
A: Most people can tolerate 4-6G briefly, while trained fighter pilots can handle up to 9G with special equipment.

Q2: How does G-force affect vehicle design?
A: Higher G-forces require stronger materials, better traction, and may affect fuel efficiency.

Q3: When would I change the gravity value?
A: Only for calculations on other planets (e.g., 3.71 m/s² for Mars).

Q4: How do I convert km/h to m/s?
A: Divide km/h by 3.6 (e.g., 100 km/h = 27.78 m/s).

Q5: What's the relationship between speed and G-force?
A: G-force increases with the square of velocity - double the speed means 4x the G-force.
