Current unit: Dynamics (Forces) in 2D
- Physics 12 Attendance
- Sit according to the chart
- Get a computer and log in
- Be ready to work when the second bell goes
- Assignment – Modelling 2D Dynamics with Excel
- Choosing the values for the parameters of Part 2
- All the parameters in your model must be non-zero (and not so close to zero that they are basically zero)
- The parameters in your model must be reasonable
- Emerging/Developing
- Use a time of 10 seconds
- Choose the other parameters so that the object accelerates
- Graph the acceleration/velocity/displacement (as separate graphs) as θ (theta) ranges from 0 to 360 degrees
- 3 graphs total
- Proficient
- Use a time of 10 seconds
- Choose the other parameters so that the object has a positive final velocity for some values of alpha and a negative final velocity for other values of α (alpha)
- Graph the acceleration/velocity/displacement as α ranges from 0 to 360 degrees
- 3 graphs total
- Extending
- Use a time of 10 seconds
- Choose the other parameters so that the object has a positive initial velocity and a negative final velocity
- Perform a numerical analysis to determine the acceleration/velocity/displacement of the box
- Create 3 separate sheets with different time increments – 100 ms, 10 ms, and 1 ms
- For each sheet
- Create column headers for time, acceleration, velocity, and displacement
- Add time data from 0 seconds to 10 seconds in the appropriate time increment
- In the t=0 row, input the initial conditions (displacement is zero, velocity is v0, and acceleration is calculated using your model)
- In the next row, calculate the displacement, velocity, and acceleration based on the values from the previous row
- Continue this procedure row-by-row, until you have reached 10 seconds
- Graph the acceleration, velocity, and displacement as time ranges from 0 to 10 seconds
- 9 graphs total
