Quick guide

How to use this calculator

  1. Choose the physical relationship and solve direction that match the known measurements rather than forcing unlike quantities into one formula.
  2. Enter every unit, sign, reference direction, geometry, material property, fluid property, temperature basis, coefficient, and idealization explicitly. The calculator normalizes compatible quantities internally and exposes intermediate values.
  3. Use reconciliation and companion outputs to catch entry mistakes, then retain the stated model boundary. A theoretical result is not a design approval, material certificate, equipment rating, or safety determination.

Calculation method

How the projectile motion calculator works

Provide the complete ideal trajectory summary visitors normally calculate in several separate steps.

Resolve v₀ into components. y=h+vᵧt−½gt²; the positive landing-time root sets range x=vₓt. Peak occurs when vertical velocity reaches zero.

Worked example

Projectile Motion example

At 30 m/s and 40° from level ground under 9.80665 m/s², the ideal range is about 90.4 m.

Resolve v₀ into components. y=h+vᵧt−½gt²; the positive landing-time root sets range x=vₓt. Peak occurs when vertical velocity reaches zero.

Supported inputs

Precision and limits

Engineering-model boundary

The model assumes uniform gravity, level landing reference, no aerodynamic drag or lift, no wind, and a point projectile. It is not a ballistics, weapon, sports-performance, or safety predictor.

Units and precision

Calculations normalize compatible inputs to SI, retain working precision, and round only for display. Very small and large nonzero values use scientific notation; displayed digits cannot create accuracy beyond the entered measurements and properties.

Decision boundary

This page solves the declared idealized relationship only. Verify applicable material data, operating conditions, geometry, loads, coefficients, standards, codes, manufacturer requirements, uncertainty, and professional approval before consequential use.

Category ownership

Generic mechanics, materials, fluid, aerodynamic, wave, and thermodynamic relationships live here. Trade-specific pipe, HVAC, motor, electrical, construction, automotive, radiation, statistical, chemical, and astronomical workflows remain with their established categories.
