- 1. Imagine: Looking for a friend who is sick whose house is 5 kilometers away from the school… Search for your lost brother or sister to unknown place 4 kilometers from the market… Listen to the radio on the weather forecast of the coming typhoon but was not
- 2. SCALARS versus VECTORS To which way will he pass in order to catch up
- 3. In Physics, everything must be specified. Each quantities must be described according to its characteristics and behavior. One of which is through directions. Considered the example of a moving typhoon and a tornado… A typhoon or a tornado is unpredictable in nature. They should be monitored every now and then in
- 4. What really happened during the typhoon “FRANK”? FRA NK Weather forecast by PAGASA is very important in cases like this, since it serves as the eye of the public to
- 5. SCALARS and VECTORS How important are the directions? To best understand this, let’s associate direction to scalars and vectors. With this, we would know if to what quantity it is very important. “What Scalars and Vectors?” Scalars are quantities having numerical values but do not need to be specified it its movement to where it is headed to or located.

- 7. Directions in VECTORS Basically, there are four (4) known directions: They are: 1. NORTH 2. SOUTH 3. EAST 4. WEST Four (4) other directions were base on the known directions. These other
- 8. SCALARS and VECTORS NW SW NE SE W E N S
- 9. SCALARS and VECTORS Scalars can be represented as: Vectors can be represented as: Length of the line is the magnitudewith no direction. Length of the line is the magnitudeand arrowhead points the direction.
- 10. SCALARS and VECTORS Vectors can also be plotted in a Cartesian coordinate system; or simply known as x – y coordinate system. y x Vectors expressed in 4 or 8 directions can also be plotted using x and y axis. y- axis can be either north or south; x-axis can be either
- 11. SCALARS and VECTORS Vectors may exist in 2 or even more.
