Objective: In this lab/simulation we will look at the power of simulations to validate calculations and/or the needs to often perform estimates, in these cases a simulation is given some initial conditions. In physics, as well as other sciences and engineering we often develop simulations to solve problems that do not readily have closed form mathematical solutions. This us allows one to simulate the response of designs of instruments and mechanisms to external forces and stimuli such as vibration, shock, thermal changes, movement of objects through various medium (i.e. drag), etc. For example, the drag, a car experiences when travelling at speed due to air resistance, or the resistance a boat experiences moving through water. Other examples might include the resistance of blood flowing through arteries and veins as a diagnostic for medical conditions. One of the key confidence tests for a simulation is to test the simulations results against known solutions. In addition, to using these known conditions to test the validity of a simulator the simulator is often used to validate calculations, especially those involving complex calculations. In this lab/simulation, we will solve several questions, and then input the results of the calculation to validate the calculated solution. We will also explore using a simulation designed for a particular set of conditions and adapting it for other situations by simply adjusting the initial conditions and/or looking at the results at various time steps while interpreting the result between the time steps.

Computer and Internet access to use the following simulation: https://ophysics.com/k7.html1) Start the simulation by clicking of the link above or by cutting and pasting the link into your browser. You should get a screen similar to figure 1 below (the annotations in the call out boxes will not be visible. You may also need to increase the size of your browser window to see the entire simulation. oPhysics: Interactive Physics Simulations Motor Drawing Toth Fun Mell Kinematics in One Dimension: Two Object System Run Pause Car Controls for setting initial Position, velocity and Reset accelerations.

Class Exercise Using the Simulation to Validate Free Fall: Q6: A stone is thrown vertically upward with a speed of 24.0 m/'s. 1. How fast is it moving when it is at a height of 13.0m? Speed: m/s 2. How much time is required to reach a height of 13.0m? m/s m/s3. Why are there 2 different times? Make sure to validate this on the simulation. 56: Run the simulation to verify your answers using the blue car. 1. Enter the initial position of the car in the Blue Car X, box on the simulation 2. Enter the initial speed of the car in the Blue Car Vo box on the simulation. 3. Enter the acceleration due to gravity (-9.8m/s') in the Blue Car a box on the simulation. 4. Run the simulation. Note the simulation will not stop when the car returns to the zero position. Rather it will keep on going into a negative position. Your task is to read the graph and determine the velocity of the stone (represented by the car) when the stone reaches a height (represent by x position in simulation) of 13 m as well as the two times the stone crosses a height of 13m. Don't forget to use the readouts on the simulation to record the velocity and times. Also based on stepping back and forth through the simulation estimate the error. (Remember the simulation only gives you values at 0.1 second intervals.) when stone/car reaches 13 m : to when stone/car reaches 13 m : S Velocity when stone/car reaches 13 m on the way up: m/s Velocity when stone/car reaches 13 m on the way down: m/s Distance traveled when car reaches zero velocity xBlue: 5. Calculate the percent error between your simulated value and the value you calculated above
