Constant Velocity Motion Unit 2 Constant Velocity Motion

Bellwork Fill in the table by writing down the power (i.e. 10^4, 10^-7, etc.) and the decimal (i.e. 0.00001 or 100000) for each metric prefix PREFIX POWER DECIMAL KILO CENTI MILLI

Activity: Square Scale Draw a box on your page Centi = 10^-2 = 0.01 Milli = 10^-3 = 0.001 Kilo =10^3 = 1000
