 * Established Goals: **

 (6) Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy. The student is expected to: (A) demonstrate and calculate how unbalanced forces change the speed or direction of an object's motion; (B) differentiate between speed, velocity, and acceleration; and (C) investigate and describe applications of Newton's law of inertia, law of force and acceleration, and law of action-reaction such as in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches.
