Unit 1 Math And Measurements Flashcards
When are zeroes significant?
In between 2 numbers, and trailing zeroes when a decimal point is present
Why are sig figs important?
If you use more than your least precise measurement, you’re present your data as more specific than it was.
Charge is measured in
Coulombs
Length is measured
In meters (m)
Current is measured in
Amperes (A)
Time is measured in
Seconds (s)
Mass is measured in
Grams, BASE UNIT IS Kg
Linear graphs show
Two variables are directly proportional, rise/run for slope.
How do you calculate area under a curve?
You add the area of different shapes formed under the line
Non linear relationships can be
Exponential or Inverse
Exponential graphs are when…
The line curves up
You can fix the curve in an exponential graph by…
Squaring the x axis
An inverse graph is when…
The graph points downwards
You can make an inverted line go up by
Putting the x axis under 1 (1/x)
