WebAug 11, 2024 · Kinematics is the description of motion without considering its causes. In this chapter, it is limited to motion along a straight line, called one-dimensional motion. Displacement is the change in position of an object. The SI unit for displacement is the meter. Displacement has direction as well as magnitude. WebOrbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft.The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation.Orbital mechanics is a core discipline within space-mission design and control. WebExample Motion along a straight line in 2D Consider for illustration purposes two particles that move along a line defined by a point P and a unit vector m. We further assume that at t = 0, both particles are at point P . The position vector of the first particle is given by r 1(t) = r P + mt = (r Px + m xt)i +(r Py + m imh kentland clinic
