Hearne ISD Science Course: Physics Unit: Two Dimensional Motion, Forces & Newton's Laws TEKS Assessment Guiding Questions/ Specificity Two Dimensional Motion 4. Science concepts. The student knows and applies the laws governing motion in a variety of situations. The student is expected to: (C) analyze and describe accelerated motion in two dimensions using equations, including projectile and circular examples; (EOC Supporting Standard) (F) identify and describe motion relative to difference frames of Revised Spring 2014 Guiding Questions What are the horizontal and vertical components of velocity? How does gravity affect velocity in the horizontal and vertical directions? What does a force diagram tell you? Specificity Students should be able to predict the horizontal range.
