→ To measure the exact position of the projectile it is necessary to create a position box→ click on the object→ enter Measure → Position →All→ in the Position box that appears click on “rot” to turn it off. This measurement isnot required since our object has no rotation.→ We are now able to run the simulation and track the path taken.→ click RUN (note: the RUN button will change to a STOP button once started)→ after approximately 2.0s stop the motion and hit RESET→ In the bottom left corner there appears a tracking deviceBrings the objects back to the starting position (rewind)Run the objects through the motion againAdvances the motion frame-by-frame (slow motion)Rewinds the motion frame-by-frame→ Advance the motion frame-by-frame by clicking→ Collect the data required to analyse the motion. The x-axis represents the horizontalmotion and the y-axis represents the vertical motion.→ keep in mind that the time for each point occurred at 0.100s intervals→ record the x and y position of each point by advancing frame-by-frame andreading the co-ordinates from the position box.→ record all values in the data table provided.→ Once all data has been collected minimize Working Models and enter GraphicalAnalysis.→ open a file marked “projecti.dat” (this contains a template of the necessarygraphs)→ plot the position-time and velocity-time graphs for the horizontal and verticalaspects of motion. You will obtain four graphs in all, two for horizontalmotion and two for vertical motion.→ Remember to use the curve fitting options to obtain a line of best fit for eachgraph.- 14 -
