How to Use
Select your event
Choose shot put, discus, javelin, or hammer. Each has different typical velocities and optimal angles.
Adjust release parameters
Use the sliders to set release velocity and angle. Experiment to see how changes affect distance.
Set release height
Enter your release height in meters (typically 1.6-2.2m depending on height and technique).
How It Works
d = vₓ × t = v·cos(θ) × (v·sin(θ) + √(v²sin²θ + 2gh)) / g
Variables:
v = release velocity (m/s)
θ = release angle (degrees)
h = release height (m)
g = 9.81 m/s² (gravity)
This formula calculates the horizontal distance traveled when an object is launched from height h at velocity v and angle θ, accounting for the time until it returns to ground level.
Frequently Asked Questions
What factors affect throwing distance?
The three main factors are release velocity (speed of the implement at release), release angle (optimal is around 35-42° depending on event), and release height (taller throwers have an advantage). Air resistance also plays a role, especially for discus and javelin.
Why isn't the optimal angle 45 degrees like in basic physics?
The classic 45° applies only when release and landing heights are equal. Since throwers release above ground level, the optimal angle is lower—typically 35-42° depending on the event and release height. This allows the implement to travel further before landing.
How does release velocity affect distance?
Velocity is the most important factor. Distance increases roughly with the square of velocity, so small increases in release speed produce significant distance gains. A 10% increase in velocity can add 20%+ to the throw distance.
Does this calculator account for air resistance?
This calculator uses ideal projectile motion physics without air resistance. Actual distances will vary due to drag (especially for discus and javelin), spin effects, and implement aerodynamics. Use it for understanding relationships, not exact predictions.
What release velocities do elite throwers achieve?
Elite shot putters release at 13-14 m/s, discus throwers at 24-26 m/s, javelin throwers at 28-30 m/s, and hammer throwers at 27-30 m/s. These velocities are developed through technique, strength, and years of training.
