We study theoretically and numerically the velocity dynamics of fully chaotic time-dependent shape-preserving billiards. The average velocity of an ensemble of initial conditions generally asymptotically follows the power law v =nβ with respect to the number of collisions n. If a shape of a fully chaotic time-dependent billiard is not preserved it is well known that the acceleration exponent Taking this into account, we show that to the leading order the average velocity v(n) as a function of the number of collisions n obeys a power law v∝n 1/6 thus, the Fermi acceleration exponent is β = 1/6, which is in excellent agreement with the numerical calculations of the fully chaotic oval billiard, the Sinai billiard and the cardioid billiard.

We consider both the static and time-dependent plane. We study the affect of different parameters that control the geometry of the billiard in this model. We consider variations of different parameters of the model and describe how the particle trajectory is We consider a slowly rotating rectangular billiard with moving boundaries and use canonical perturbation theory to describe the dynamics of a billiard particle.

Fiz. 116, 1781–1797 共November 1999兲 The paper is devoted to the problem of Fermi acceleration in Lorentz-type dispersing billiards whose boundaries depend on time in a certain way. Two cases of boundary oscillations are considered: the stochastic case, when a boundary changes following a random function, and a regular case with a boundary varied according to a harmonic law.

Vered Rom-Kedar 2011-02-18 The acceleration mechanism has a natural thermodynamical interpretation and is applied to a hot dilute gas of repelling particles. DOI: in billiards [1], and then make the boundary oscillate. The particle may gain or lose energy upon collision, depending on whether or not the particle and the boundary move towards each other [2]. friction force vector, and therefore the cue ball acceleration, are constant both magnitude in and direction, the cue ball trajectory will be parabolic, just as with any constant acceleration motion (e.g., projectile motion), until the sliding ceases, in which case the CB heads in a straight line. TP A.4. contains the full derivation. acceleration. In chaotic billiards, even if the boundary velocity is a smooth function of time, the incidence angle of a particle can be treated as a random parameter.

A class of nonrelativistic particle accelerators in which the majority of particles gain energy at an exponential rate is constructed. The class includes ergodic billiards with a piston that moves adiabatically and is removed adiabatically in a periodic fashion. The phenomenon is robust: deformations that keep the chaotic character of the billiard retain the exponential energy growth. The Parts of a smooth successful stroke are developing the ability to move the cue back and forth in a straight line; understanding that a slight acceleration in your stroke (regardless of how hard you are hitting the cue ball) provides more consistent contact on the cue ball; and we must have the core understanding that the only thing we really Billiards is very similar in that a key to be able to play at a high level is the ability to hit a smooth, consistent stroke on the cue under high pressure situations. If you do not put the hard work in learning and practicing, you won't be able to focus solely on the shot at hand.

At contact, the cue decelerates, then accelerates briefly before decelerating to a stop. Since the deceleration at contact lasts for 7ms (for this stroke), it appears to reflect the compression of the tip and movement of the flesh of the hand.
