Physics simulator
See physics happen: launch a ball at a speed and angle you choose, on Earth, the Moon or Mars, with or without air drag, and see range, max height and flight time — or swing a pendulum and compare its period with the formula.

Questions
Why is 45° the farthest?
Without drag and from ground level, range peaks at 45°. Turn on drag or raise the launch point and watch the best angle change.
Why is the real pendulum slower?
T = 2π√(L/g) holds for small angles only; larger swings take longer — the simulator computes it exactly.
How accurate?
Projectiles use the formulas; with drag, small time steps (0.005 s).
