Lind Dr. Kun Yang Dr. David Van Winkle Today: Kinematics in two dimensions kinematical equations vectors projectile motion preview: Newtons Laws PHY 2053C College Physics A Fall 2004 L4Ch3,4 Free Fall Galileo Galilei, 1564-1642 Free Fall is one-dimensional motion with a constant, negative acceleration. This means the acceleration is always pointing downward ! Galileo observed that all objects fall with the same, constant acceleration g = -9.80 m/s 2 (downward) (as long as air-resistance is small) 2 Introduction Projectile Motion 2 special cases of 1d-motion: motion with constant velocity (e.g. horizontal motion on a frictonless rail) motion with constant acceleration (e.g. free fall) Projectile Motion is combination of horizontal constant velocity and vertical free fall 2d-Motion Motion in the horizontal and vertical directions are independent . X and Y are independent (linked only by time)....
