Force and Motion
7.P.1- Understand motion, the effects of forces on motion and the graphical representations of motion.
7.P.2- Understand forms of energy, energy transfer and transformation, and conservation in mechanical systems.
7.P.1.3 Illustrate the motion of an object using a graph to show a change in position over a period in time.
7.P.1.4 Interpret distance versus time graphs for constant speed and variable motion.
7.P.2.1 Explain how kinetic and potential energy contribute to the mechanical energy of an object.
7.P.2.2 Explain how energy can be transformed from one form to another (specifically potential energy and kinetic energy) using a model or a diagram of a moving object (roller coaster, pendulum, or cars on ramps as examples).
7.P.2.3 Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass.
7.P.2.4 Explain how simple machines such as inclined planes, pulleys, levers, and wheel and axels are used to create mechanical advantage and increase efficiency.
