Westchester Community College College Physics 1 Lab 1 Projectile Motion Purpose Investigate the relationship between different quantities describing projectile motion. Procedure Go to: https://www.thephysicsaviary.com/Physics/Programs/Labs/ProjectileLab/ Part 1 Horizontally Launched Projectile – Fixed Height 1. Set the height to 30 and the angle to 0° . These variables will not be altered for the rest of this part of the experiment. 2. Fire the projectile at 8 -10 different speeds including a speed of 0 /. For each speed record in Table 1 (see the Data Sheet) the speed you fired the projectile with and the horizontal distance it travelled . 3. Using Excel or Google Sheets, plot horizontal distance vs initial velocity . 4. Add trendline and display the equation of line on your graph . Take a screenshot of the graph and include in the lab report. 5. Use = and compare to the equation of the trendline. What physical quantity does the slope represent? Part 2 Horizontally Launched Projectile – Fixed Initial Velocity 1. Set the initial projectile speed to 25 / and the angle to 0° . These variables will not be altered for the rest of this part of the experim ent. 2. Fire the projectile at 8 -10 different heights including a height of 0 . For each height record in Table 2 (see the Data Sheet) the height from which you fired the projectile and the time of flight. 3. Using Excel or Google Sheets, plot h eight vs time . 4. Add trendline and display the equation of line on your graph. The equation should be in the form: = where is position and is time. Take a screenshot of the graph and include in the lab report. Westchester Community College College Physics 1 Lab 2 5. Compare the equat ion of the trendline to the kinematics equation: = . Using = find the acceleration due to gravity and record in the Data Sheet. 6. Calculate the percent error using = . /. Record in the Data Sheet. Part 3 Projectile Fired at an Angle from Ground 1. Set the initial projectile speed to 28 / and the height to 0 . These variables will not be altered for the rest of this part of the experiment. 2. Fire the projectile at angles ranging from 0° to 90° usin g a 5° increments. For each angle record in a data table the angle from which you fired the projectile and the horizontal distance it travelled. 3. Using Excel or Google Sheets, plot range vs angle . Take a screenshot of the graph and include in you r lab report. 4. What is the angle for which the range is maximum? Part 4 Projectile Fired at an Angle from > 1. Fire the projectile from a height greater than zero. Use the simulation to find the angle that maximizes the range. Take a screenshot for the angle that maximizes the range and include in your lab report. 2. For = 0 the firing angle than optimizes a projectile’s range is 45° . For landing below the firing point, as in Step 1, would you expect the firing angle which optimizes the range to be greater than or less than 45 °? Carefully explain why.
