CH3 Motion in Two or Three Dimensions
 


Goals for Chapter 3

 · To study position, velocity, and acceleration vectors

 · To apply position, velocity, and acceleration insights to projectile motion （抛物运动）

 · To extend our linear investigations to uniform and nonuniform circular motion（圆周运动）

 · To investigate relative velocity
