Newton's laws of motion and gravitation describe the relationships among forces acting on and between objects, their masses, and changes in their motion - but have limitations Evidence Outcomes 21st Century Skill and Readiness Competencies Students Can: Gather, analyze and interpret data and create graphs regarding position, velocity and acceleration of moving objects (DOK 1-3) Develop, communicate and justify an evidence-based analysis of the forces acting on an object and the resultant acceleration produced by a net force (DOK 1-3) Develop, communicate and justify an evidence-based scientific prediction regarding the effects of the action-reaction force pairs on the motion of two interacting objects (DOK 1-3) Examine the effect of changing masses and distance when applying Newton's law of universal gravitation to a system of two bodies (DOK 1-2) Identify the limitations of Newton's laws in extreme situations (DOK 1) Inquiry Questions: How can forces be acting on an object without changing the object's motion? Why do equal but opposite action and reaction forces not cancel? Relevance & Application: Newton's laws are used in a variety of design processes such as vehicle safety, aerospace, bridge design and interplanetary probes. An understanding of forces leads to safer building designs such as earthquake-safe buildings. Forces present in the earth lead to plate tectonics. Nature Of: Use an inquiry approach to answer a testable question about an application of Newton's laws of motion. (DOK 1-4) Share experimental data, respectfully discuss conflicting results, and analyze ways to minimize error and uncertainty in measurement. (DOK 2-3) Differentiate between the use of the terms "law" and "theory" as they are defined and used in science compared to how they are used in other disciplines or common use. (DOK 1-2) Use technology to perform calculations and to organize, analyze and report data. (DOK 1-2)
