Which angle provides the greatest range? Which provides the least? Based on your results, which angle should give the greatest range for projectile motion? - The 45 degree angle produced the greatest range for which the object will travel. I would say the least is the 30 degree mark. Based off my results the greatest range will be the 45 degree for the object to travel the greater distance. 2. What role does air resistance play in affecting your data? - It causes the object to not be able to travel as far since air resistance causes the overall ability of the object to travel a distance. ©eScience Labs, 2018
