 SC (3) 4. Define force and motion. Identifying forces that change an object's position or motion Examples: lifting, pushing, pulling Identifying sources of friction Examples: rubbing hands together, applying sandpaper to wood Describing the force of gravity 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) Physics 2. Define the law of conservation of momentum. Calculating the momentum of a single object Calculating momenta of two objects before and after collision in one-dimensional motion SC (9-12) Physics 4. Describe quantitative relationships for velocity, acceleration, force, work, power, potential energy, and kinetic energy. 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) Physical Science 9. Use mathematical equations (e.g., (m1v1 + m2v2) before = (m1v1 + m2v2) after) and diagrams to explain that the total momentum of a system of objects is conserved when there is no net external force on the system. a. Use the laws of conservation of mechanical energy and momentum to predict the result of one-dimensional elastic collisions. 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) Physics 3. Evaluate qualitatively and quantitatively the relationship between the force acting on an object, the time of interaction, and the change in momentum using the impulse-momentum theorem.
