1.5 - Math Review

The Goal

• review and discuss standard units of measurement and the mathematics utilized in physical mathematics

An Example

A good example of the combination of all of these is the speed of light: 

• 299 792 458 m/s. This is a derived unit (meters per second).

• It can also be written in km/s: 299 792.458 km/s.  This has a unit prefix - kilo.

• Written in scientific notation:  2.99792458 x 10⁸ m/s

  • But that's longer!  You're right. Normally we would round a bit:  2.998 x 10⁸ m/s

Your Task

• Log onto a computer

• Go to Hapara and complete the "1.5 - Math Review" task

  • answer the questions in the document

  • submit it when you are finished (due by next class)

Extra

• Have you completed the ISU item(s) for this week?
