Relative Motion in 2D The description of the motion of an object in two or three dimensions depends on the choice of the coordinate system. Figure 4.8 shows two reference frames in two dimensions. The vectors r PA and r PB are the position vectors of object P in reference frame A and in reference frame B, respectively. Vector r BA is the position of observer B (located at the origin of reference frame B) in frame A. The position vector of the object P in reference frame B can be obtained from the position vector in reference frame A:

Unformatted text preview: Figure 4.8. Reference Frames in Two Dimensions. The velocity and acceleration of the object P in reference frame B can be obtained by differentiating the position vector of P in reference frame B with respect to time: If the observer in reference frame B is moving with a constant velocity with respect to an observer in reference frame A, the acceleration of the object P measured by observer A will be the same as the acceleration measured by observer B....
