Definition
- Rearrange the equation to the form y = mx + b.
- Figure out how the slope and y-intercept relate to the constants.
- Draw a best fit line.
- Calculate the slope and y-intercept from your line.
- (If needed) calculate the slope and y-intercept.
For example, in this problem 1/b = slope and a = y-intercept. |

Definition
- Find the data point where F = 30 N.
- Figure out if you're using vertical or horizontal error bars.
- Determine how long the error bars are at F = 30 N.
- State answer with correct units.
In this case, the units would be m/s because you're finding the absolute uncertainty in speed. You'd use the vertical error bars. |

Definition
- Find the data point where F = 20 N.
- Find the percentage uncertainty in that point.
- Determine the value of v.
- Determine the value of ∆v (use the error bars).
- Calculate ∆v/v.
- Multiply the percentage uncertainty by 2.5 (the exponent).
- Calculate the absolute uncertainty in v2.5.
- Calculate the value of v2.5
- Use the equation % in v2.5 = ∆(v2.5)/v2.5

Definition
Some rules to follow:
- Your line can be straight or curved.
- Send the line through all of the error bars.
- Extend your line all the way back to the y axis.
- If you can send the line through the origin, do that.
- If your line is curved, make sure it's smooth & not bumpy.

Definition
- Rearrange the equation to the form y = mx + b.
- Determine what the slope and y-intercept are.
- State how the slope & y-intercept are related to the constants. (Ex: b is the slope & a is the y-intercept.)
- Draw a max slope line and a min slope line.
- Calculate the max & min values of slope/y-intercept.
- Use: absolute uncertainty = (max – min)/2
