Projectile Motion Calculator
Find range, peak height, and flight time from speed and angle.
The arc of a throw
Launch anything into the air and its path is a predictable parabola set by its speed and angle. This calculator finds how far it goes, how high it climbs, and how long it stays aloft.
A 20 m/s launch at 45 degrees travels about 40.8 metres and peaks near 10.2 metres. The 45-degree angle maximizes range without air resistance, which is why it is the classic answer.

Frequently Asked Questions
What does it assume?
A projectile launched from ground level with no air resistance, under constant gravity.
What does it compute?
The horizontal range, the maximum height reached, and the total time in the air.
Which angle gives the most range?
45 degrees, with no air resistance. The tool shows how range falls off as you move away from that angle.
