The flight path angle is the angle between the orbiting body's velocity vector (equal to the vector tangent to the instantaneous orbit) and the local horizontal. Under standard assumptions of the conservation of angular momentum the flight path angle ϕ {\displaystyle \phi } satisfies the equation: [ 6 ]
In astrodynamics, an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time.Under standard assumptions, a body moving under the influence of a force, directed to a central body, with a magnitude inversely proportional to the square of the distance (such as gravity), has an orbit that is a conic section (i.e. circular ...
A similar definition holds for θ 2, the angle of the second particle. If the path of the first particle is described in the form r = g(θ 1), the path of the second particle is given by the function r = g(θ 2 /k), since θ 2 = k θ 1. For example, let the path of the first particle be an ellipse
A study finds that people who engage in just 30 minutes of exercise per week see modest improvements in body weight and body fat but for clinically significant improvements they need a higher average.
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.
A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
An injury-ravaged Detroit defense – 13 players from that side of the ball are on injured reserve – likely will have trouble slowing Allen and the league's No. 2 scoring offense.
If one reference frame assigns precisely the same time to two events that are at different points in space, a reference frame that is moving relative to the first will generally assign different times to the two events (the only exception being when motion is exactly perpendicular to the line connecting the locations of both events).
