$Y:\How to solve 2 dimension relative velocity problems.wpd$

KinematicsConclusion:Make a concise summary of the properties of the graphs from the motion studied in bothmodels. Include tiny sketches, general equations, meanings of slopes, intercepts and areas.type of motion properties of x-t graph properties of v-t graphConstant velocity- travelling with“steady” (unchanging)paceSlope =Y int =General Eqn =Slope =Y int =Area =General Eqn =Constantacceleration- travelling with“steadily” changing paceSlope =Y int =General Eqn =Slope =Y int =Area =General Eqn =From now on we will refer to steady paced motion as Uniform Linear Velocity (ULV) andsteadily changing pace motion as Uniform Linear Acceleration (ULA).Briefly sum up the results of this lab.a. In your own words, state what it means to travel with constant acceleration andconstant velocity.b. Explain how to calculate velocity based on a position -time graph.c. Explain how to calculate acceleration based on a velocity-time graph.d. Explain how to get displacement from a velocity-time graph.e. Comment on any errors affecting your results.- 12 -
Projectile SimulationSituation: Projectile motion is simply a case of simultaneous motion in two directions. Weneed to assess the motion in each direction.Theory: Divide and conquer. Analyzing what happens in two directions simultaneously isdifficult for us to do. However, if we can look at the vertical motion seperately from thehorizontal motion, then we have a chance at interpreting this event.Procedure: To aid in the study of projectile motion we will use a program called WorkingModels 3.0.3 which will allow us to create and launch our own model. As well, the programwill allow us to analyse the resulting two-dimensional motion map. The followinginstructions will help you create your own motion map.→ Open Working Model 3.0.3 and maximize the window.→ To create a reference frame for the motion of the object we need a co-ordinate system→ enter View → Workspace → XY Axes→ enter View → Workspace → Gridlines→ To create an object click the circle located on the toolbar (about the third down), returnto the screen and “click and drag”. Try not to create an object that is to big because itbecomes more difficult to track.→ Now we need to move our object to the origin and give it an initial velocity.→ scroll down until the origin of the XY axes is in the lower left corner of thewindow→ double click on the object so that a “properties” window appears→ set the x and y co-ordinates to 0 m. (Note that the object is now positioned at theorigin)→ give the object an initial velocity by setting the horizontal and verticalcomponents. (Try v x = 5 m/s and v y = 7 m/s)→ close the properties window→ Now we need to track the motion of the projectile→ enter World → Accuracy→ in the box that appears change the animation step from the Automatic to 0.1s→ enter World → Tracking → every frame→ enter Measure → Time- 13 -
