PI.3.2 Develop graphical and Inertial mass mass of a body as determined by Cause and effect – mathematical representations the second law of motion from the acceleration that describe the relationship of the body when it is subjected to a force that among the inertial mass of an is not due to gravity object, the total force applied One dimension ability to move in only one – and the acceleration of an dimension, linear movement object in one dimension where one or more forces is applied to the object and apply those representations to qualitatively and quantitatively describe how a net external force changes the motion of an object. PI.3.3 Construct Vectors quantity having direction as well as Scale, proportion, and – diagrams using appropriately magnitude quantity labeled vectors with Magnitude numerical quantity or value – magnitude, direction, and Direction course which something moves Energy and matter – units to qualitatively and Units scale in which a numerical value is – quantitatively analyze a expressed scenario and make claims (i.e. Forces strength or energy as an attribute of – develop arguments, justify physical action or movement assertions) about forces exerted on an object by other objects for different types of forces or components of forces. PI.3.4 Understand Newton’s Newton’s third law of motion when a force Scale, proportion, and – third law of motion and acts on a body due to another body, then an quantity describe the interaction of equal and opposite force acts simultaneously on two objects using Newton’s that body Systems and system third law and the Action-reaction pairs for every action force, models – representation of there is an equal and opposite force reaction pairs of forces.
