Quick answer

Ignoring air resistance, a projectile's range is v²sin(2θ)/g, maximised at a 45° launch angle.

R = v² sin(2θ) / g

Frequently asked questions

Why is 45° optimal?

It balances vertical hang time against horizontal speed — only true from level ground.

Does this include drag?

No, it assumes a vacuum; real ranges are shorter.

What do I need to enter into the Projectile Motion Calculator?

Just 3 values: launch speed, launch angle, launch height. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.

How does the Projectile Motion Calculator work out the answer?

Ignoring air resistance, a projectile's range is v²sin(2θ)/g, maximised at a 45° launch angle. It applies the formula R = v² sin(2θ) / g and shows the working so you can check each step by hand.

Is the Projectile Motion Calculator free, and do I need an account?

It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
