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

Definition
 Draw the data point at the specified x and y values. Based on the graph's scale, determine how long the error bars should be. Draw the error bars.
