AP Physics 1: Hidden Derivations They Expect You to Know

If you’re preparing for AP Physics 1, this is the video you don’t want to skip. In this lesson, we derive all the key formulas that are NOT given on the formula sheet, so you can stop memorizing and start actually understanding where everything comes from. Knowing these derivations will help you tackle unfamiliar problems and boost your confidence on exams. We go step-by-step through the most important results, including: Time of projectile motion Range equation Maximum height of a projectile Gravitational field Speed of a satellite Kepler’s Third Law Maximum speed around a curve Minimum speed to complete a loop Escape speed Total spring energy in oscillation Maximum speed in SHM Speed at any point in oscillation Torricelli’s Theorem By the end of this video, you’ll be able to rebuild these formulas from basic principles—so even if you forget them, you’re never stuck. Perfect for: AP Physics 1 students studying for tests or the AP exam Anyone who wants a deeper understanding of physics concepts Last-minute review without rote memorization Video Chapters 0:00 Intro 0:42 Time of projectile in air 7:45 Range equation 10:33 Maximum height of a projectile 14:55 Gravitational field 17:11 Speed of a satellite 19:46 Kepler’s Third Law 23:30 Maximum speed around a curve 26:58 Minimum speed to complete a loop 29:29 Escape speed 34:09 Total spring energy in SHM 37:10 Maximum speed in SHM 39:07 Speed at any point in SHM 44:10 Torricelli’s Theorem
