1.2 Representations of Motion

SCIENCE PRACTICES

• Modeling

• 1.2 The student can describe representations and models of natural or man-made phenomena and systems in the domain.*

• 1.4 The student can use representations and models to analyze situations or solve problems qualitatively and quantitatively.

Mathematical Routines

• 2.2 The student can apply mathematical routines to quantities that describe natural phenomena.

• 2.3 The student can estimate quantities that describe natural phenomena.*

Argumentation

• 6.4 The student can make claims and predictions about natural phenomena based on scientific theories and models.

LEARNING OBJECTIVE

4.A.1.1 Use representations of the center of mass of an isolated two-object system to analyze the motion of the system qualitatively and semi-quantitatively. [SP 1.2, 1.4, 2.3, 6.4]

4.A.2.1 Make predictions about the motion of a system based on the fact that acceleration is equal to the change in velocity per unit time, and velocity is equal to the change in position per unit time. [SP 6.4]

4.A.2.3 Create mathematical models and analyze graphical relationships for acceleration, velocity, and position of the center of mass of a system and use them to calculate properties of the motion of the center of mass of a system. [SP 1.4, 2.2]
