Excerpt from the Book
INTRODUCTION
Sir Isaac Newton (1642 – 1728) was the first to introduce calculus to physics. He used calculus to explain and proof the basic formulae relating to linear motion connecting the following terms: Linear acceleration (a), time (t), initial velocity (v) final velocity (v) and distance(s).
These formulae/formulas include 1. V= u + at, 2. S = ½ (v + u) + , 3. S = ut + ½ at2, 4. V2 = u2 + 2as. This research work is aimed at pounding several ways in which the equation of linear motion can be derived or proven.
Calculus motion is not usually emphasized by teachers except for advanced studies for those who are interested in Newtonian Physics. The approach of using calculus notations should be used frequently and regularly to encourage students at all levels of learning, anytime Newtonian Physics is taught.
This research work introduces a new innovation by expressing equations of linear motion in matrix form – in 2 X 2 matrix, 3 X 3matrix, 4 x 4 matrix Etc. It also expresses other physical quantities such as: work, power, pressure, impulse, linear momentum and force in a matrix forms.
