Alabama Course of Study Alignments and/or Professional Development Standard Alignments:

 SC (9-12) Physical Science 6. Identify characteristics of gravitational, electromagnetic, and nuclear forces. SC (9-12) Physical Science 7. Relate velocity, acceleration, and kinetic energy to mass, distance, force, and time. Interpreting graphic representations of velocity versus time and distance versus time Solving problems for velocity, acceleration, force, work, and power Describing action and reaction forces, inertia, acceleration, momentum, and friction in terms of Newton's three laws of motion Determining the resultant of collinear forces acting on a body Example: solving problems involving the effect of a tailwind or headwind on an airplane Solving problems for efficiency and mechanical advantage of simple machines SC (9-12) Physical Science 12. Identify metric units for mass, distance, time, temperature, velocity, acceleration, density, force, energy, and power. SC (9-12) Earth and Space Elective 1. Describe sources of energy, including solar, gravitational, geothermal, and nuclear. SC2015 (9-12) Physical Science 7. Analyze and interpret data for one- and two-dimensional motion applying basic concepts of distance, displacement, speed, velocity, and acceleration (e.g., velocity versus time graphs, displacement versus time graphs, acceleration versus time graphs). SC2015 (9-12) Physical Science 8. Apply Newton's laws to predict the resulting motion of a system by constructing force diagrams that identify the external forces acting on the system, including friction (e.g., a book on a table, an object being pushed across a floor, an accelerating car). SC2015 (9-12) Physics 1. Investigate and analyze, based on evidence obtained through observation or experimental design, the motion of an object using both graphical and mathematical models (e.g., creating or interpreting graphs of position, velocity, and acceleration versus time graphs for one- and two-dimensional motion; solving problems using kinematic equations for the case of constant acceleration) that may include descriptors such as position, distance traveled, displacement, speed, velocity, and acceleration. SC2015 (9-12) Physics 2. Identify external forces in a system and apply Newton's laws graphically by using models such as free-body diagrams to explain how the motion of an object is affected, ranging from simple to complex, and including circular motion. a. Use mathematical computations to derive simple equations of motion for various systems using Newton's second law. b. Use mathematical computations to explain the nature of forces (e.g., tension, friction, normal) related to Newton's second and third laws. SC2015 (9-12) Environmental Science 1. Investigate and analyze the use of nonrenewable energy sources (e.g., fossil fuels, nuclear, natural gas) and renewable energy sources (e.g., solar, wind, hydroelectric, geothermal) and propose solutions for their impact on the environment.
