7 calculators
Acceleration & drag
Drag testing, acceleration rates, and factor relationships.
Reconstruction calculator workspace
Work the calculation. Keep the supporting math.
Crash Science brings 51 reconstruction tools into one guided workspace. Choose the problem you need to solve, enter the measured values, and preserve the calculation when it belongs to a case.
51guided calculators
Organized by the reconstruction question rather than a required sequence. Inside the member workspace, each calculator guides the required values and units, checks the entries, and presents the result with its supporting work.
5 calculators
Surface adjustments
Braking, slope, grade, and superelevation adjustments.
8 calculators
Conversions & energy
Common reconstruction units, work, energy, and center of mass.
4 calculators
Grade & superelevation
Signed roadway grade, cross-slope, and angle conversions.
5 calculators
Speed loss & combined speed
Skid, combined-segment, and equivalent-speed calculations.
12 calculators
Time, distance & motion
Distance, time, velocity, acceleration, and related arrangements.
3 calculators
Radius & critical speed
Chord, middle ordinate, curve radius, and yaw speed.
4 calculators
Airborne motion
Fall, vault, launch angle, trajectory, and apogee methods.
3 calculators
Rollover & avoidance
Rollover propensity, rollover speed, and avoidance distance.
Inside the member workspace
More than a formula list.
The value is the controlled workflow that turns recorded inputs into reviewable, reusable case work.
Use the right values and units.
Clear field labels, supported units, entry checks, and method-specific warnings help prevent avoidable input errors.
See and preserve the supporting work.
The workspace presents conversions, substitutions, intermediate math, the full-precision result, assumptions, and limitations while you work.
Carry compatible results forward.
Save full-precision results to a case and offer compatible values to later calculations without retyping them.
Keep an analysis that can be reviewed.
Retain input sources, revisions, calculator versions, dependencies, and report-ready output with the case record.
Crash Science membership
The working calculator library stays inside the professional workspace.
Solo and Team plans include the calculators, saved case variables, calculation history, and reporting tools.
Quick calculation
Work one method without opening a case.
Members can enter values manually and review the complete calculation without saving the result.
Case-connected analysis
Preserve results that belong to the case.
Saved results retain their full precision and supporting calculation. Compatible values can be offered to later equations, but the user still confirms that the evidence and assumptions support reuse.
