−|The image on the side, spanning half a second, was captured with a stroboscopic flash at 20 flashes per second. During the first 1⁄20 of a second the ball drops one unit of distance (here, a unit is about 12 mm); by 2⁄20 it has dropped at total of 4 units; by 3⁄20, 9 units and so on. Check [http://en.wikipedia.org/wiki/Equations_for_a_falling_body here] for a more detailed description.

−* '''Website interactives/ links/ simulations'''
−* '''Process (How to do the activity)'''
−#Project the picture for the class and discuss the following questions
−* '''Developmental Questions (What discussion questions)'''
−#Where is the ball at time = 0?
−#In the first (1/20)th of a second, what is the distance travelled by ball?
−#In the second (1/20)th of a second, what is the distance travelled by ball?
−#How does the distance fallen increase with time?
−#What can you say about the motion?
−* '''Evaluation (Questions for assessment of the child)'''
−* '''Question Corner'''
−Will the ball also attract the Earth and produce an acceleration?
