Free Fall
• Free fall – in the absence of air resistance, all objects dropped near the surface of the Earth fall with a constant acceleration
• Denoted by the symbol g• g = - 9.81 m/s2 (negative because
acceleration is directed downward)

Graphical Analysis of velocity vs. time graph
• Straight line slope indicates acceleration is constant (fig. 2-16)• There is an instant where velocity is 0
(when ball reaches peak of upward motion)
