Spacecraft flight dynamics is the application of mechanical dynamics to model how the external forces acting on a space vehicle or spacecraft determine its flight path. These forces are primarily of three types: propulsive force provided by the vehicle's engines; gravitational force exerted by the Earth and other celestial bodies; and ...
t. e. Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation.
e. In celestial mechanics, escape velocity or escape speed is the minimum speed needed for an object to escape from contact with or orbit of a primary body, assuming: Ballistic trajectory - no other forces are acting on the object, including propulsion and friction. No other gravity-producing objects exist.
Emblem. Military unit. The United States Space Force(USSF) is the United States Armed Forces' space serviceand one of the eight uniformed services of the United States. It is one of two independent space forces in the world. [6] The United States Space Force traces its origins to the Air Force, Army, and Navy's military space programs created ...
Trajectory. A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously.
v. t. e. Classical mechanics is a physical theory describing the motion of objects such as projectiles, parts of machinery, spacecraft, planets, stars, and galaxies. The development of classical mechanics involved substantial change in the methods and philosophy of physics. [ 1 ] The qualifier classical distinguishes this type of mechanics from ...
The United States Space Force is organized by different units: the Space Staff, the field commands, and the space deltas. The Space Force is organized as one of two coequal military service branches within the Department of the Air Force, the other being the United States Air Force. Both services are overseen by the Secretary of the Air Force ...
In physics and engineering, a free body diagram (FBD; also called a force diagram) [ 1 ] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).
