Projectile Motion Experiment Calculator
Input launch speed, angle, and gravity to compute ideal projectile results (no air resistance).
How to Use This Calculator
1
Measure launch speed
Use a motion sensor or compute from known height and horizontal range in tests.
2
Set angle and gravity
Angle measured from horizontal; use g = 9.81 m/s² unless otherwise required.
3
Compare outputs
Time, range, and peak height assume no air resistance and level ground.
Formula
T = 2 v₀ sinθ / g, R = v₀² sin(2θ)/g, H = v₀² sin²θ / (2g)
Classical projectile motion neglecting air resistance, launch and landing at same elevation.
Frequently Asked Questions
What if launch and landing heights differ?
These formulas change; you must solve the kinematic equations including initial and final heights.
How big is air resistance error?
It depends on speed and drag; for small speeds and dense objects, the error can be modest; for light balls, significant.
