  1. Purpose of article

The complexity that kinematic studies pose to learners remains a disturbing fact to Ganci and Ganci (2010), due to the availability of simple and yet to be explored experiments. The authors of “A measure of g: in search of simplicity” aim at educating the audience that there are indeed cheaper methods of establishing the gravitational velocity while appreciating the existing ones. In doing so, they introduce the stick ice-lolly stick model that uses two marbles or iron balls in trajectory motion to establish the gravitational acceleration.

  1. Fundamentals

As long as the initial velocity at which parabolic trajectory occurs is parallel to the horizontal plane then it is provided that free fall time is a function of gravity and distance.

Library Assignment= height of free fall

Library Assignment 1= gravitational acceleration

Library Assignment 2= is time consumed

This principle is applied as the main concept towards achievement of the major objective of this study. Secondly, wave technology is applied through use of creative wave studio to demonstrate the falling time that parabolic trajectory consumes with respect to acceleration due to gravity.

  1. Materials

The materials employed for this study include; two glass marbles or iron balls depending on availability, wooden ice-lolly stick, personal computer connected with microphone and installed with creative wave studio without forgetting a table or bench.

  1. Procedure

To begin with the marble iron balls are pressed at both ends of the wooden ice-lolly stick in order to create concave impressions for purpose of resting the balls. The stick is placed at the corner of the table with a small overhang while ensuring that equilibrium is maintained. The ball on the section projecting to the table is pushed towards the floor causing disturbance of equilibrium due to its trajectory motion. Lack of balance fells the overhanging ball in a parabolic trajectory manner simultaneously hitting the floor with the ball rolled from the table and sound recorded by creative wave studio via microphone. This experiment is repeated with balls of different masses to establish the degree of variance. Further suggestions are made for similar experimental procedure to be repeated by felling marble or iron balls off a pressed table surface near the edge in a parabolic trajectory in a bid to come up with parameters for gravitational acceleration investigation as a matter of comparison with the initial methodology.

Furthermore, this method uses zero-cost equipment which can be easily deployed for study both at school and home while adding value to pedagogy.

is not explained for the purpose of audience learning. It could be a good idea for the authors to indicate the applicability of this equation within the context of study.Library Assignment 7It is important that as much as this experiment is zero-cost be formalised in a manner that the students have to take it more seriously. It is also worth criticizing the fact that Ganci and Ganci (2010), state that this experiment is zero-cost whereas the personal computer hardware and software mentioned could be substituted by designing an alternative zero-cost hardware. In addition the equation of uncertainty
