GRAVITATION
First click on the Animation 1 or Animation 2 button, then on "(re)play". The animation shows how the vertical position, speed and acceleration of a freefalling body change as the time changes. Position is given in metres and time in seconds.
Note: Right-click on a graph to open a new resizable window giving a better view.

Your challenge is:
  1. What do the graphs of position, speed and acceleration tell you about freefalling motion?
  2. Determine the value of gravitational acceleration, g. (This is a science experiment! Take readings from the animation, Make a table of the position of the ball at times 0, 1, 2, 3, 4, ... seconds and find patterns in the table …)
  3. Find the formula for each of the two animations.
  4. If the motion continues, where is the blue ball after 5 seconds?   
  5. If the motion continues, where is the red ball after 5 seconds?
