Projectile motion: the two components are independent
Year 12 Physics · ideal model, no air resistance · ax = 0, ay = −9.8 m/s² · vx = v cos θ stays constant, vy = v sin θ − gt

Set speed, angle and height, then press Launch. After the flight, drag the scrubber to freeze any moment — try the apex.

Range vs launch angle
one gold dot per completed launch
Dots accumulate for the current speed and height. Changing either clears the chart — the shape of the range-versus-angle curve belongs to one speed-and-height family, so dots from different families must not be mixed.
