Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.

Question

is
Vectors are represented by arrows. The length of the arrows indicate the magnitude of the
vector, and the arrowhead points to the direction of the vector. In our example, the displacement
is drawn at a scale: 1 cm = 10 cm, directed to the east.

The speed of an object is a measure of how fast it moves. If the object is moving from on
position to another in a measured time, its average speed v is obtained by dividing the distan
traveled by the time taken to cover the distance. In mathematical form,
Speed

Name METRIC CONVERSIONS Hour Sometimes you need to change meters to centimeters, or kilometers to meters. Here is an easy way to do that: Here are the metric units of length written from largest to smallest. km hm dam m dm cm EXAMPLE: To convert meters (m) to millimeters (mm) you start at m and move to the right. Count the number of jumps you make to get to mm. 1 jump 2 jumps 3 jumps km hm dam m dm cm mm Since you moved 3 jumps to the right, move the decimal point 3 places to the right. (If you run out of numbers, add a zero for each jump you make after the last number.) 2.05 = 2050 2.05m = 2050mm 123 Problems: Fill in each blank for the problems below. 1. 410 cm = 3. 5. 7. 9. 11. 13. 15. 17. 19. 35 ml = 12 km = 3.4 kg = 157m= 13.5 mm = .69 km = 2500 ml = 27 mg= .135 km = mm g L km g cm cm mm L m mm 2. 4. 6. 8. 10. 12. 14. 16. 18. 20. 16700 m 455 L= .00005 km = 3.57 cm = 157 kg = 15.2 km = 1m= 1000 m .09 cm 107 m = 1 of 1 mm ml m m g cm cm km km Dimensional Analysis review 1.
