## Description

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.

## Tools

### get_arrow_mass_properties


### get_ballistic_performance


### get_spine_impact_analysis


## Prompt Examples

**Prompt:** 
```
What is the FOC and total weight for an arrow that is 30 inches long, with a balance point 5 inches from the nock, a 125gr point, 15gr/in shaft, 50gr insert, 20gr nock, and 10gr fletching?
```

**Response:** 
```
The total weight is 655 grains and the FOC is 14.5%.
```

**Prompt:** 
```
Calculate the kinetic energy and momentum for a 450 grain arrow shot at 300 fps.
```

**Response:** 
```
The kinetic energy is 31.25 ft-lbs and the momentum is 0.41 slug-fps.
```

**Prompt:** 
```
If I increase my point weight from 100gr to 125gr on a 30 inch shaft weighing 15gr/in, how much will the spine weaken?
```

**Response:** 
```
The spine weakening ratio is 1.08.
```

## Frequently Asked Questions

**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.
