This page is a simplified collision sketch, not a verified reconstruction of a real incident. Its vehicle labels and fire percentage should not be treated as evidence about actual people, injuries, or events. We can still inspect how its arithmetic works. Two assumed masses and speeds produce initial kinetic energy; a combined momentum calculation produces a common speed, and their energy difference feeds several illustrative outputs. The default masses are nineteen hundred fifty and seventeen hundred twenty kilograms. Speeds of thirty two and forty eight miles per hour become fourteen point three one and twenty one point four six meters per second. One half mass times speed squared gives roughly two hundred and three hundred ninety six kilojoules. Speed is squared, so doubling speed while keeping mass fixed quadruples that vehicle’s initial energy. These bars use one pixel per kilojoule. The source angle parameter is seventy five degrees, but its velocity formula uses the complement: cosine and sine of fifteen degrees. Both vehicles therefore have positive horizontal momentum in the arithmetic, rather than a seventy five degree separation. The common velocity is about seventeen point three one horizontally and two point six zero vertically, in meters per second. Its calculated final energy is about five hundred sixty two kilojoules. Subtracting from the initial total gives about thirty three kilojoules, the exported rounded result. The reported peak value divides the larger velocity change by an assumed ninety five millisecond duration, then by gravity. It rounds to four point eight g here. This is not a measured occupant load. Crush is point zero eight times the square root of energy lost, capped at one point four meters. The fire label is simply energy lost divided by three hundred twenty, times one hundred, rounded and capped. It gives ten percent here, but that number is an unvalidated score, not a real probability. Changing friction or impact offset alters the visual motion and contact geometry, but neither input appears in the exported energy formula. The export recomputes its arithmetic even before a collision is shown. On screen the main telemetry remains zero until visual contact; the exported values can already be nonzero. Use presets, native controls and the case report to distinguish predicted model numbers from animation state. None of this verifies a real incident or establishes vehicle safety.
