Students use the mathematical representations to ● predict how the force of Gravity will be affected when one or more of the factors are changed (e.g. multiplied by 2, divided by 3) ● predict how the electric force will be affected when one or more of the factors are changed (e.g. multiplied by 2, divided by 3) Analysis Students use the analysis of the ● given mathematical models to identify that the ratio of gravity and electric force between objects with a given charge and mass is a pattern that is independent of distance ● mathematical constants to determine a comparative strength between the gravitational force and electric force Students use the mathematical representations of the gravitational and electric force to ● describe why the gravitational force is only attractive while the electric force is both attractive and repulsive Students use the given formulas ● as evidence to describe how the potential energy changes as a result of distance. ● phenomenon of the photoelectric effect to determine how it supports the argument that electromagnetic radiation can be described by a particle model. ● claims and reasoning for modeling electromagnetic radiation as both a wave and particle, considering the transfer of energy and information within and between systems, and why for some aspects the wave model is more useful and for other aspects the particle model is more useful to describe the transfer of energy and information. ● the magnitude and direction of the gravitational force and the electric force around an object. ● a vector feld model to represent the gravitational and electric felds around an object. Students describe what each data set represents. Explanations include: ● how changing positions and velocities connect to a change in energy Identifying Relationships Students use tools, technologies, and/or models to analyze the data and identify and describe relationships in the datasets, including: ● the change in the energy of the objects, given the initial and fnal positions and velocities of the objects. Students analyze data to identify effects of: ● changing the potential energy of objects interacting through the gravitational or electric felds depends on the distance between objects Interpreting Data Students use the analyzed data to support a claim Standard 3.3 Organizing Data Students organize data that represents:. ● the two objects’ positions and velocities
