In this lesson, we explore how quadratic equations model projectile motion and how to use them to answer real-world questions. You’ll learn how to find the maximum height of a projectile using the vertex formula:
t = −b / 2a
Then we use the quadratic formula to determine when the projectile hits the ground (when the height equals zero).
This video covers:
✔️ How to interpret projectile motion with quadratic functions
✔️ Using −𝑏/2𝑎 to find the time of maximum height
✔️ Plugging the time back in to find the actual max height
✔️ Using the quadratic formula to find when the object lands
✔️ Step-by-step worked examples
Perfect for Algebra 2, Precalculus, STAAR prep, SAT prep, or any student learning real-world applications of quadratics.
