Part 1 — Horizontal & vertical kinematics • Part 2 — Falling with air resistance
Part 1 — SUVAT Equations
Sign convention: downward = positive. Enter a negative initial velocity to throw the object upward — it will rise, stop in mid-air, then fall back down.

Part 2 — Falling Object with Air Resistance
Earth gravity fixed at 9.81 m/s². Drag model: F = ½·ρ·Cd·A·v² (ρ = air density).
