G-Force Results
Formula used: G = (v₁ - v₀) / (t × g)
Motion type: Linear acceleration/deceleration
Severity: Comfortable for most people
Physiological Effects
Example Calculation
Emergency Car Braking
Scenario: Car traveling at 60 km/h suddenly stops
Initial velocity (v₀): 60 km/h = 16.67 m/s
Final velocity (v₁): 0 m/s
Time (t): 1 second
Calculation
G-force = (v₁ - v₀) / (t × g)
G-force = (0 - 16.67) / (1 × 9.81)
G-force = -16.67 / 9.81
G-force = -1.70g
Moderate negative G-force during emergency braking!

G-Force Tips
Positive G pushes you into your seat
Negative G pulls you out of your seat
Trained pilots can withstand up to 9g
G-suits help prevent blood pooling
Sustained G-forces are more dangerous
Understanding G-Force
What is G-Force?
G-force (gravitational force equivalent) is a measurement of acceleration experienced by an object, expressed as a multiple of Earth's gravitational acceleration (9.81 m/s²). When you experience 2g, you feel twice as heavy as normal.
Types of G-Force
- •Positive G (+Gz): Acceleration toward the feet, blood pools in lower body
- •Negative G (-Gz): Acceleration toward the head, blood rushes to brain
- •Lateral G: Side-to-side acceleration, less physiologically stressful
Calculation Methods
Linear Motion:
G = (v₁ - v₀) / (t × g)
Circular Motion:
G = v² / (r × g) = ω² × r / g
Where: g = 9.81 m/s²
