I can make qualitative (non-mathematical) predictions about the relationship between variables. I can record and represent data in a meaningful way. I can represent data graphically and determine the equation that models the data. I can include appropriate constants and units in an equation derived from a linear graph.

I can describe the differences and similarities between static friction and kinetic friction. I can use the coefficient of friction to calculate the frictional force acting on an object. Given a diagram or description of an object in equilibrium, including the forces acting on the object, I can, determine the magnitude and direction of a “missing’ force required to keep the object from changing its motion I can identify and compare Newton’s Third Law pairs of forces acting on objects. 3 Uniformly Accelerated Particle Model I can determine the instantaneous velocity of an object using 3 different methods I can determine the displacement of an object using 3 different methods I can determine the acceleration of an object using 5 different methods Given a position vs. time graph, I can o Describe the motion of the object o Draw the corresponding velocity vs. time and acceleration vs. time graphs o Draw a motion map for the object Given a velocity vs. time graph, I can o Describe the motion of the object o Draw the corresponding position vs. time and acceleration vs. time graphs o Draw a motion map for the object o Write a mathematical representation of the motion of the object I can solve a variety of accelerated motion problems using graphical or algebraic methods 4 Unbalanced Force Particle Model I can use Newton’s 2nd Law to qualitatively describe the relationship between mass, acceleration, and net force. Given a velocity vs. time graph, I can draw the corresponding acceleration vs. time and force vs. time graphs. I can determine the net force acting on an object using three different methods. I can solve quantitative problems involving forces, mass and acceleration using Newton's 2nd Law. I can continue to use the kinematical models from previous units to determine the velocity, time elapsed, or displacement of an object, once I have determined the acceleration from the net force acting on the object. 5 Two Dimensional Motion Particle Model I can I can use multiple representations to describe the motion of an object in “free –fall”. I can use video analysis techniques to produce position-time and velocity-time graphs which represent the behavior of an object moving in two dimensions. I can determine which models are appropriate to describe the horizontal and vertical motion of an object moving in two dimensions. I can draw a motion map for an object undergoing parabolic motion, with velocity and acceleration vectors for both dimensions. I can draw a force diagram for an object undergoing parabolic motion. I can solve problems involving projectile motion to determine the initial velocity the time of flight the height the point where the projectile lands speed at impact I can explain what effect the mass of a projectile has on its time of flight. 6 Energy Storage and Transfer Model I can make distinctions between energy storage and energy transfer I am able to recognize and identify energy storage mechanisms: Gravitational Kinetic Elastic internal I can recognize the universal, fundamental nature of energy as opposed to different “forms” of energy I can use Hooke’s Law to analyze elastic energy systems I can recognize and identify models of energy transfer: Working Heating radiating I can use representational tools to analyze a system in terms of energy storage and transfer pie charts bar graphs energy flow diagrams system schema diagrams I can analyze a system of energy interactions appropriately according to the system designation I can explain friction as a mechanism for dissipating energy I can determine the quantity of energy transferred between various accounts (kinetic, elastic, gravitational, and internal energy) during an interaction I can explain “working” as energy transfer to/from system via an external force and calculate the amount of work done on a system I can define and calculate power involved with energy transfer 7 Momentum Transfer Model I can use velocity – mass bar graphs to illustrate conservation of momentum I can define momentum and distinguish between momentum and velocity.
