  3. Driving Question • How can we, as physicist, create a Safe Speed limit proposal to submit to the National Highway Traffic Safety Administration?

  4. Mission • Your mission is to create a “Safe Speed Limit Proposal.” that tells the NHTSA what the maximum speed limit should be on major highways. • Your proposal should be supported by scientific principles. • Newton’s 3 laws of motion • Speed, Velocity, & Acceleration • Balanced & Unbalanced forces. • You will submit your proposal to the National Highway Traffic Safety Administration (NHTSA). • You will also create a keynote, power point or video presentation to present your findings. It must include the following: • Key points from proposal • Graphs illustrating speed, velocity and acceleration. • Animations or video clips demonstrating Newton’s Laws of Motion.

  5. Guiding Questions • How do interacting forces affect the speed of an object’s motion? • How do interacting forces affect the direction of an object’s motion? • How do different forces change and object's motion? • How can one differentiate between speed, velocity and acceleration on a graph? • How can one determine speed or velocity of an object given distance and time? • How are speed, velocity, and acceleration represented on a distance vs .time graph? • What is the difference between speed, velocity, and acceleration? • How does the mass of a body at rest affect its tendency to remain at rest? • How does the force required to move an object change with mass? • How does the force acting on an object affect its tendency to remain at rest?

  6. Timeline • Tuesday 10/30 – Entry Event, Group Contract • Wednesday 10/31 – Knows/Need to knows, Rubrics, & Project Team Work Plan • Thursday 11/1 – Research • Friday 11/2 – Simple Machine Quiz / Research • Monday 11/5 – Write Proposal • Tuesday 11/6 – Write Proposal • Wednesday 11/7 – Work on Presentation • Thursday 11/8 – Finalize Presentations • Friday 11/9 - Presentations
