4) orbit angular velocity 轨道角速度 5) Track critical velocity 轨道临界速度 1. By use of this formula and the superposition principle,the relationships between track critical velocity and track vibration boom induced by a single wheel load and high speed trains are investigated and the ...
Finally, substituting the formula (Equation 2.64) for the period T of a circular orbit, T=2πr32/μ, yields t=θ2πT or, θ=2πTt The reason that t is directly proportional to θ in a circular orbit is simply that the angular velocity 2π/T is constant. Therefore the time Δ...

(2) The Canadian Space Agency gives you a second assignment.A satellite is in circular orbit around Mercury.It travels at a distance of 124 km above the surface of Mercury and its period of rotation is 1 hour 31.5 minutes.(a) Estimate the Mass of Mercury.State which formula(s) you ...
innermost stable circular orbitneutral test particlerotating sourceIn 1998, Shibata and Sasaki [Phys. Rev. D 58, 104011 (1998)] presented anapproximate analytical formula for the radius of the innermost stable circularorbit (ISCO) of a neutral test particle around a massive, rotating and deformed...
We then apply this formula to a particle which plunges from the innermost stable circular orbit (ISCO) and collides with another particle near the horizon. It is found that the maximum value of the CM energy E_{m cm} E_{m cm} is given by E_{m cm}/(2m_{0})\\simeq 1.40/\\...
This formula can also be derived in a different way, using vectors. If you take the position vector to be r⋅ur, whereur=cosθ,sinθ, then the (linear) velocity is given by v=ⅆrⅆt=r⋅uθ⋅ⅆθⅆt, ...
The total energy of a body in a circular orbit can be calculated using the formula E = -GmM/2r, where G is the gravitational constant, m is the mass of the orbiting body, M is the mass of the central body, and r is the radius of the orbit. What is the significance of the tota...
1), \(\overrightarrow{\beta }\) is the electron velocity normalised by the velocity of light, and ω is the electron angular velocity. The right sides of Eqs (1) and (2) represent the emitter time \(t\text{'}\), which is related to the observer time t by Eq. (3). An ...
