Term

How do you solve this problem?

Definition
  1. Rearrange the equation to the form y = mx + b.
  2. Figure out how the slope and y-intercept relate to the constants.
  3. Draw a best fit line.
  4. Calculate the slope and y-intercept from your line.
  5. (If needed) calculate the slope and y-intercept.

For example, in this problem 1/b = slope and a = y-intercept.

Definition
  1. Find the data point where F = 30 N.
  2. Figure out if you're using vertical or horizontal error bars.
  3. Determine how long the error bars are at F = 30 N.
  4. 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
  1. Find the data point where F = 20 N.
     
  2. Find the percentage uncertainty in that point.
    1. Determine the value of v.
    2. Determine the value of ∆v (use the error bars).
    3. Calculate ∆v/v.
       
  3. Multiply the percentage uncertainty by 2.5 (the exponent).
     
  4. Calculate the absolute uncertainty in v2.5.
    1. Calculate the value of v2.5
    2. Use the equation % in v2.5 = ∆(v2.5)/v2.5

Definition

Some rules to follow:

 

  1. Your line can be straight or curved.
  2. Send the line through all of the error bars.
  3. Extend your line all the way back to the y axis.
  4. If you can send the line through the origin, do that.
  5. If your line is curved, make sure it's smooth & not bumpy.

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