How do I calculate the total weight of my arrow?

You can use the `get_arrow_mass_properties` tool by providing the length, component weights, and balance point.

Can I predict how a heavier point affects my arrow's flight?

Yes, the `get_spine_impact_analysis` tool calculates the spine weakening ratio when you increase the point weight.

How is kinetic energy calculated?

The `get_ballistic_performance` tool calculates kinetic energy in ft-lbs using the arrow's mass and the bow's velocity.

More Details Connect to Claude

A deterministic physics engine for archery. Use get_arrow_mass_properties to find the Front of Center (FOC) and total weight. Use get_ballistic_performance to calculate kinetic energy and momentum based on bow speed. Use get_spine_impact_analysis to predict how changing point weight affects arrow stiffness.
