Kick Off Questions

  1. If you were not able to complete part b last time, take some time and complete it now
  2. Copy the given code into one of your group's Glowscript accounts, and add comments as to what the given code is doing.

Project 2: Learning goals

  • Predict the motion of a single-particle system executing constant velocity or constant acceleration motion using appropriate representations (this includes verbal, graphical, diagrammatic, mathematical, and computational representations).
  • Collect, analyze, and evaluate data to determine the type of motion and the properties of the motion of a single-particle system.
  • Evaluate the applicability/limitations of models and the validity of predictions for different types of motion.
  • Apply the momentum principle (Δ→p=→FΔt; d→p=→Fdt) iteratively/computationally to predict the motion or determine the properties of motion/net force acting on a single-particle system where the net force is not constant (e.g., due to spring-like restoring forces or dissipative drag forces).

Project 2: Learning Concepts

  • Forces cause changes in momentum
  • Kinematic Equations - Constant Acceleration
  • Gravitational Force Near Earth
  • Vector Components
  • →Fnet=m→a=Δ→pΔt
  • Iterative Prediction of Motion

Project 2: Part C: Escape from ice station McMurdo

Surprisingly enough hovercrafts are an expensive piece of kit. Your employer, the Carver Media Group, is concerned by the happenings at the McMurdo ice station and would like you to produce an accident report detailing the events after you lost control of your hovercraft. The accident report should include a detailed computational model that provides the projected motion of the runaway hovercraft.

In general, do not erase your boards untile your small group instructor has had a chance to go over this with you.

Wrap Up Questions for part C:

  1. Is your model realistic? Why or why not?
  2. How could you make your model more realistic?
  3. Before erasing your board or moving to the next part, talk to your small group instructor about your solution and your responses to the two part C wrap up questions

HINT: each of these wrap-up questions are evaluation-focused. In each of these projects you should try to evaluate both your solution and your model. Each of these are parts included in our three group projects. Use our in-class problems to get practice evaluating.

Project 2: Part D: Escape from ice station McMurdo

The Carver Media Group is now asking for an accident report for the your hovercraft as well. They want to you simulate the events from the point at which the two hovercrafts meet to when the hovercraft reached the water, however, they want you to model the hovercraft as if it had left the cliff at angle of 27 degrees from the ground. They want this model to be in the same model as the model for the runaway craft.
