Calculation Formula

a_l = v² / r

Where:
a_l = Lateral acceleration (m/s²)
v = Vehicle speed (m/s)
r = Turning radius (m)

What is Lateral Acceleration?

Lateral acceleration (often denoted as al) is the acceleration experienced by an object moving in a curved path. In vehicle dynamics, it represents the force pushing occupants outward during a turn.

How to Use the Calculator

  1. Enter the vehicle speed in kilometers per hour (km/h)
  2. Enter the turning radius in meters
  3. Click the "Calculate" button to compute the lateral acceleration
  4. The results will be displayed in both m/s² and g units

Understanding the Formula

The calculator uses the formula: al = v²/r, where:

  • al is the lateral acceleration
  • v is the vehicle speed in meters per second
  • r is the turning radius in meters

Practical Applications

Lateral acceleration is an important parameter in vehicle design, performance tuning, and safety assessments. It affects:

  • Handling and stability
  • Cornering limits
  • Occupant comfort and safety
  • Tire performance

Note: For more accurate results in real-world scenarios, factors like tire grip, suspension geometry, and aerodynamic forces should also be considered.
