G Force Formula:
From: | To: |
G force (gravitational force equivalent) measures acceleration relative to Earth's gravity. For spinning objects, it represents the centripetal acceleration expressed in multiples of Earth's gravity (9.81 m/s²).
The calculator uses the g force formula:
Where:
Explanation: The formula calculates centripetal acceleration (v²/r) and converts it to g-force by dividing by Earth's gravitational acceleration.
Details: G force calculation is crucial for designing amusement park rides, analyzing vehicle performance, understanding physiological effects on pilots/astronauts, and engineering rotating machinery.
Tips: Enter velocity in m/s and radius in meters. Both values must be positive numbers greater than zero.
Q1: What is a typical g-force range for humans?
A: Most people can tolerate 4-6g for short periods. Fighter pilots may experience up to 9g with special training and equipment.
Q2: How does g-force affect the human body?
A: High g-forces can cause vision changes (greyout/blackout), loss of consciousness, and physical stress due to blood being forced away from the brain.
Q3: What's the difference between positive and negative g-force?
A: Positive g-force pushes you into your seat (common in upward acceleration), while negative g-force pulls you out of your seat (common in downward acceleration).
Q4: Can g-force be less than 1?
A: Yes, in microgravity environments (like orbit) or during freefall, g-force approaches zero. Negative g-values indicate acceleration opposite to gravity.
Q5: How is g-force measured in practice?
A: Accelerometers are typically used to measure g-forces directly in vehicles, amusement rides, and aerospace applications.
