25) When we talk about free fall, we ignore air resistance.
26) Acceleration of object in free fall is about g= 10 meters/sec 2
27) Kinematics is the study of motion Galileo discovered these relationships.
28) There are 6 kinematics variables and 2 kinematics equations
29)Kinematics variables for free falling object, Y = final position in y direction Y o = initial position in y direction V oy = initial velocity in y direction V fy = final velocity in y direction a y = -g t = time elapsed
30) What is meant by “-g”? The object is accelerating in the negative direction
