Steps 1–3 Free Steps 4–6 Paid
STEP 1
Orient / Definition: what is time of flight?
Free
Build a precise understanding of what time of flight means and why it is controlled by vertical motion, not by horizontal motion.
Prompt preview will appear here.
Goal: understand time of flight as the total time a projectile remains in the air from launch to landing.
STEP 2
Conceptual grounding: vertical motion decides the flight time
Free
Build intuition for why the projectile stays in the air as long as its vertical motion takes, and why equal launch and landing heights create a useful symmetry.
Prompt preview will appear here.
Goal: understand why time of flight comes from the vertical equation and when symmetry helps.
STEP 3
Real-world connection: when symmetry works and when it breaks
Free
Connect time of flight to realistic projectile situations, including angled launches, horizontal launches, and cases with different launch and landing heights.
Prompt preview will appear here.
Goal: know when you can use a symmetry shortcut and when you must solve the full vertical equation.
STEP 4
Check your understanding: mini-quiz (answers hidden until you reveal)
Paid
Try each question first. Answers + feedback appear only when you click Reveal answer. This prevents accidental spoilers and builds real exam readiness.

Goal: attempt first → then reveal and learn from your mistakes.
STEP 5
Practice: solve time-of-flight problems step-by-step
Paid
Work through carefully chosen projectile problems involving same-height launches, horizontal launches, and different-height landings.
Prompt preview will appear here.
Goal: reliably choose the correct vertical equation and solve for total time in the air.
STEP 6
Summary & reflection + Exploration / “simulation” prompts
Paid
Consolidate the key ideas, then explore how launch angle, launch height, gravity, and vertical speed affect the total time in the air.
