PHY9A Lecture Notes - Lecture 1: Free Fall
Document Summary
Free fall is a special case of motion under gravity, where an object falls freely under the influence of gravity without any air resistance. In this article, we will provide detailed notes on free fall, including its key concepts, equations, and examples. Free fall occurs when an object falls freely under the influence of gravity, without any air. The acceleration due to gravity (g) is a constant value that is approximately equal to 9. 8 m/s^2. The direction of the acceleration due to gravity is always downward, towards the center of the. The velocity of an object in free fall increases uniformly with time. The displacement of an object in free fall increases with time, and is given by the equation: y = resistance. The velocity of an object in free fall is given by the equation: v = gt, where v is the velocity, g is the acceleration due to gravity, and t is the time elapsed.
