Introduction
Topics
Scalars and vectors Measurement of length and time 
Description
Play with the vector sum Model. The simulation randomly generates different vector A and B every time the reset is clicked. You can drag the vector midpoint to re-position drag the vector head to re-size There are also 3 examples of how this simulation can be used by Teacher Mr. Ezzy Chan. There is also 3 components representation to connect with the related simulation on components of a vector. Dragon the plotting panel to reposition the center to have a better view of the resultant vector.
Challenge:
Take an example from your usual word problem and take a picture of it and try to use the simulation to represent the word problem. After you are done, the simulation should be able to calculate as well as draw the resultant vector. send your completed picture to weelookang@gmail.com to be included as an example in this simulation-model! 
Sample Learning Goals
(f) add two vectors to determine a resultant by a graphical method (b) solve problems for a static point mass under the action of 3 forces for 2-dimensional cases (a graphical method would suffice)

Interesting Fact
This simulation is targeted for O level Physics education, built by teachers for teachers and students.
