How does the equipment type affect the calculation?

The calculation adjusts friction resistance based on whether you use a `jib` or a `board`, as they have different contact surface areas.

What is the difference between flat and kinked entry?

A `flat` entry assumes a continuous level surface, while a `kinked` entry accounts for an immediate angular change which increases initial resistance.

Can I get a full report of the rail impact?

Yes, you can use the `analyze_feature_efficiency` tool to get a holistic overview including approach speed, speed loss, exit speed, and momentum retention.

More Details Connect to Claude

This MCP server provides a physics-based calculation engine for determining rider velocity and speed loss when traversing rail features. It uses friction and balance models to calculate approach speed, speed loss, and exit speed. Use get_approach_velocity to determine safe entry speeds, calculate_speed_loss to quantify friction impact, get_exit_velocity to predict final speeds, or analyze_feature_efficiency for a complete momentum analysis.
