2.   AP  Physics Math Review

 

 Using powers of ten to describe very big and very small numbers.

 

 

Remember this stuff.

10,000 = 104

1,000 = 103

100 = 102

10 = 101

1 = 100

0.1 = 10-1

0.01 = 10-2

0.001 = 10-3

0.0001 = 10-4

 

 

30,000 = 3x 10,000 = 3x104

30,000 = 30x 1000 = 30x103

30,000 = 30,000 x 1 = 30,000x100

30,000 = 3,000,000x 0.01 = 3,000,000x10-2

 

All of the above are correct.

They all describe 30,000
