 Component of a Vector JavaScript HTML5 Applet Simulation Model by Loo Kang Wee and Fu-Kwun Hwang

## Components Vector Model also known as Sine Cosine Model

 http://weelookang.blogspot.sg/2014/10/components-vector-model.html CLICK https://dl.dropboxusercontent.com/u/44365627/lookangEJSworkspace/export/ejss_model_horizontalvertical/horizontalvertical_Simulation.xhtml author: lookang, Fu-Kwun, Andreu Glasmann, Wolfgang Christian, and Mario Belloni offline use: https://dl.dropboxusercontent.com/u/44365627/lookangEJSworkspace/export/ejss_model_horizontalvertical.zip source: https://dl.dropboxusercontent.com/u/44365627/lookangEJSworkspace/export/ejss_src_horizontalvertical.zip author of EJS 5: Paco.

## Engage:

Vectors are fundamental in the physical sciences. They can be used to represent any quantity that has magnitude, has direction, and which adheres to the rules of vector addition. An example is velocity, the magnitude of which is speed. For example, the velocity 4 meters per second upward could be represented by the vector $A_{y}$ = (0,4) (in 2 dimensions with the positive y axis as 'up'). Another quantity represented by a vector is force, since it has a magnitude and direction and follows the rules of vector addition. Vectors also describe many other physical quantities, such as linear displacement, displacement, linear acceleration, angular acceleration, linear momentum, and angular momentum. Other physical vectors, such as the electric and magnetic field, are represented as a system of vectors at each point of a physical space; that is, a vector field. Examples of quantities that have magnitude and direction but fail to follow the rules of vector addition: Angular displacement and electric current. Consequently, these are not vectors.

## Component:

As explained above a vector is often described by a set of vector components that add up to form the given vector. Typically, these components are the projections of the vector on a set of mutually perpendicular reference axes (basis vectors). The vector is said to be decomposed or resolved with respect to that set. For simplicity, let's assume x and y direction as the reference axes, referring to the model above.
the equations for the components are:

$A_{x} = A cos( \theta)$

$A_{y} = A sin( \theta)$

## Model:

This model uses the following equations:

## Length or Magnitude |A|:

The length or magnitude or norm of the vector a is denoted by |A|.

$|A| = \sqrt {( A_{x}^{2}+A_{y}^{2})}$

## Angle:

The angle in radian of the vector that makes with the positive x axis is

$\theta = tan^{-1} (\frac {A_{y}}{A_{x}})$

the conversion to degree is

$\theta_{degree} = (tan^{-1} (\frac{A_{y}}{A_{x}}) )( \frac{180}{\pi})$

or

$\theta_{degree} = ( \theta )( \frac{180}{\pi})$

in the design of the slider values which shows in degree, the equation that converts back from degree to radian is used

$\theta = ( \theta_{degree} )( \frac{\pi}{180})$

when i made this model from a fresh ejss, the following works were reference from

1. lookang, Fu-Kwun http://weelookang.blogspot.sg/2010/06/ejs-open-source-represent-vector.html
2. andreu glasmann, wolfgang christian, mario belloni Physlet Physics illustration 3.1. found in the Davidson College Digital Library for Physlets View the Physlet Two-Dimensional Kinematics Illustrations Package

1. remade everything from lookang, Fu-Kwun http://weelookang.blogspot.sg/2010/06/ejs-open-source-represent-vector.html
2. re-used some elements from andreu glasmann, wolfgang christian, mario belloni Physlet Physics illustration 3.1. found in the Davidson College Digital Library for Physlets View the Physlet Two-Dimensional Kinematics Illustrations Package to speed up development as per legally allowed by creative commons attribution, sharelike. i esepcially liked the ability to interact with the vector now, thanks to Prof Paco author of EJS 5.
3. added ability to animate, thanks to idea from https://www.desmos.com/ and http://www.geogebra.org/
4. added angle thanks to Prof Fu-Kwun guidance on some other works some years back!

## update 29/8/2016

MOE administers the Innergy Awards to recognise innovative projects from that have brought about significant benefits to stakeholders. This award is administered for MOE HQ, Schools and Stat Boards. total of 47 applications and 15 Innergy Awards (HQ) winners.
 Project Division Award Open Source Physics at Singapore (OSP@SG) ETD/CPDD Gold

I would like to thank the project team of Lily and Victor for their support who gave lots of valuable inputs to strengthen the write-up in this INNERGY award which I believe presented ETD projects in the best light. The judges particularly valued the fact that making interactive resources was done by education officers in ETD, CPDD and schools, networking with experts in the world, as oppose to paying vendors to make them.
I also thank Mr Chua for his vision and timely suggestions to brand the amazing work we do in TFL, service schools and MOEHQ.
I also want to thank Ms Chan, aka my savior in 2008-09 for putting me and Mr Thong into the works of harnessing open technologies which took root in ETD .
Finally, I am really grateful for such a friendly and open leaders including Dr Chee, of course, to nurture this project.

## highlight the innovative aspect of your project and how it has benefited the intended stakeholders.

This 2016 submission is vastly different and an expanded from my earlier Gravity Physics by Inquiry in 2012 submission as the innovativeness is on just 4 Java based simulations to address learning needs of a small topic in the A level Physics.

This OSP@SG 2016 submission is UNESCO ICT pedagogically validated, all 100+ HTML5 simulations covering large topics in O and A level Physics, 100+ Java Tracker video analysis resources covering O and A level kinematics and dynamics, 2 e-books covering 2 Advanced Level Physics topics funded by eduLab21, most of them(why not all?, not all physics can be mathematically modelled meaningfully for learning like random motion, constant rotation easier to visual than to model by students themselves etc) have the pedagogical approach called and coined by me as "mathematical modeling".

So you can see, 4 inquiry enabled Java simulation in 2012, is not the same as 100+ HTML5, 100+video analysis and 2 ebooks ,with mathematical modeling pedagogical approach.
Right?

Anyway, the main point about Open Source Physics at Singapore (OSP@SG) is to advance an inclusive and equitable quality education and lifelong learning for all and i hope that more educators will join OSP@SG so that they can also find happiness in the service of others.

## Purpose and Value of Physics

Physics is a fundamental science which is concerned with understanding the natural world. A small number of basic principles and laws can be applied to explain and predict a wide range of physical events and phenomena. The fundamental theories of physics form the bedrock of many modern technologies and are responsible for practical applications in and the advancement of several different fields of science and technology. H2 Physics exposes students to the science process skills of investigation, reasoning, analysis and evaluation, which are transferable and useful to everyday life. It also develops attitudes and dispositions such as critical thinking and logical analysis, a curious and inquiring mind, and the ability to solve problems and grasp complex concepts.

A unique feature in the study and practice of physics is the extensive use of models, especially those expressed in mathematical language, to explain observations and make predictions . A model serves as a bridge between abstract scientific theories and the observations and experiences of the real world . Models should be tested through experiments and must be consistent with available evidence. Hence, they can change and evolve with new evidence . The learner should be cognizant of the assumptions and limitations that are inherent in the use of models as they simplify complex real world phenomena . Knowledge and understanding of the use of models in the learning of physics is highly transferable to other disciplines, such as modelling of biological processes, weather patterns, earthquakes, and even the movement of people or financial markets.
