设计思想抛体运动包括平抛和斜抛运动，它是物体在重力场中最基本、最普遍的运动形式。抛体运动某些特征在生活实践中很难直接观察到，找到一种在课堂上能够真实、直观、准确反映抛体运动特征的新途径，是当前教学中急需解决的问题。笔者设计制作的抛体运动轨迹投影演示器...
Design Ideas The projectile movement consists of flat and oblique throwing motions. It is the most basic and common form of motion of an object in a gravitational field. It is difficult to directly observe some characteristics of the projectile movement in life practice. It is an urgent problem to be solved in the current teaching to find a new way that can truly, intuitively and accurately reflect the characteristics of throwing motion in the classroom. The author designed the projection trajectory projection demonstrator...
