Question

5. Use the Cricket Graph software and the Macintosh computer to graph y versus x (y is vertical axis, x is horizontal axis). a) Find the curve of best fit b) Find the equation of the curve of best fit. e) Use the equation of the curve to find vo. The coefficient of the 2 term, b, will yield vo, eg, v3. Make a list of the systematic errors that might have affected your values of vo: Would they make your results too high or too low? 1. 2. How can some of these errors be eliminated? 3. It has been assumed that air resistance (drag) forces are negligible. What effect would drag have on the trajectory of the projectile.

Explanation / Answer

5.

A)

Systematic error: The error which take place due to the defect in the measuring device affects the accuracy of experiment, this type of error known as systematic error.also known as zero error.

B)

It can be corrected by correcting the measuring devices or to avoid old devices.
