SATII物理专题分析 Two-Dimensional Motion with Uniform A

  SAT考试是美国高中生进入美国大学的标准入学考试,包括SAT1和SAT2。SAT2是专项测验,有数学、物理、化学、生物、外语等,大部分为选择题,是可以选科的。今天我们来学习SATII物理专题分析 Two-Dimensional Motion with Uniform Acceleration,希望对大家的复习有所帮助。

  If you’ve got the hang of 1-D motion, you should have no trouble at all with 2-D motion. The motion of any object moving in two dimensions can be broken into x- and y-components. Then it’s just a matter of solving two separate 1-D kinematic equations.

  The most common problems of this kind on SAT II Physics involve projectile motion: the motion of an object that is shot, thrown, or in some other way launched into the air. Note that the motion or trajectory of a projectile is a parabola.
