📖 1. Free Fall Height

🔑 Key Concepts & Definitions

• Calculation of height from distance fallen in last second: The process of determining the initial height (h) from the known distance fallen during the final second of free fall, often using equations of motion for free fall (see equations below).

• Equations of motion for free fall: Mathematical expressions describing the displacement, velocity, and acceleration of an object under gravity with no air resistance, typically given by $s = v_0 t + \frac{1}{2} g t^2$ and $v = v_0 + g t$.

• Velocity at impact in free fall: The final velocity of an object just before hitting the ground, calculated by $v = \sqrt{2 g h}$ when dropped from height h, assuming initial velocity $v_0 = 0$.

• Distance fallen in last seconds of free fall: The specific displacement during the final second of free fall, which can be derived from the total height and the velocity at that time, often used to relate the height to the distance fallen in the last second.
