Measurement of length and time## Description

A vector is a quantity that has both magnitude and direction. Displacement, velocity, acceleration, and force are the vector quantities. in simpler examples, vectors were simply directed up, down, left or right. In situations in which vectors are directed at angles to the customary x(horizontal)-y(vertical) coordinate axes, a useful mathematical trick will be employed to transform the vector into two parts with each part being directed along the coordinate axes. What if the customary x-y coordinate axes is not (horizontal) and (vertical)? Sometimes, it could be useful to resolve vectors along and perpendicular to a slope, direction of travel than always horizontal and vertical,## What is shown here?

1. What are the x and y components of the RED vector A?2. record down on a piece of paper.

3. What are the x and y components of the BLUE vector B?.

4. record down on a piece of paper.

5. now, you have the values of (Ax, Ay) = _______ and (Bx, By) = _______

## How to calculate the resultant of 2 vectors?

1. click PLAY to visualise the meaning of addition of vector A with B.2. What are the components of this vector sum?

3. How do they relate to the components of the original (RED and BLUE) vectors?

4. The vector (BLACK) sum C = (Cx, Cy) is now a vector that reaches from the tail of the first (RED) A = (Ax,Ay) vector to the head of the second (BLUE) B = (Bx,By) vector.

5. test yourself whether you have enough practice calculating C = (Cx,Cy).

## Other interesting fun activities

1. this model can be used to calculate any A & B vectors.4. explore your own vector(s) here to test your understanding.

5. leave me a Google+ comment/question/requests etc here http://weelookang.blogspot.sg/2014/10/vector-addition-model.html
