Objects in free fall accelerate at 9.8 m/s/s. Examine the motion of a ball dropped from a tall building. Consider an acceleration graph, velocity vs time graph, and a displacement vs time graph.
A ball's speed slows as it goes up and increases as it comes back down. Review definitions before graphically analyzing a projectile using a velocity vs. time graph, an acceleration vs. time graph, and a displacement vs. time graph.
The upward motion of a projectile's flight is the equal counterpart to the downward motion, allowing you to establish the zero second mark on the displacement and velocity vs. time graphs. Calculate the flight time.
Analyze a displacement vs. time graph of a falling object by calculating the gradient of a curved line. Review the topics discussed in previous "Shedding Light on Motion" videos and the upcoming episode.

In episode five of the Shedding Light on Motion series, we continue looking at graphs but pay particular attention to how graphs help us to understand the motion of objects that are either falling straight down or which have been launched vertically upwards into the air.
