Electronic stopping refers to the slowing down of a projectile ion due to the inelastic collisions between bound electrons in the medium and the ion moving through it. The term inelastic is used to signify that energy is lost during the process (the collisions may result both in excitations of bound electrons of the medium, and in excitations of the electron cloud of the ion as well).
The CSDA range is a very close approximation to the average distance traveled by a charged particle as it slows down to rest, calculated in the continuous-slowing-down approximation. In this approximation, the rate of energy loss at every point along the track is assumed to be equal to the same as the total stopping power .
As the car launches from rest, there is a large positive jerk as its acceleration rapidly increases. After the launch, there is a small, sustained negative jerk as the force of air resistance increases with the car's velocity, gradually decreasing acceleration and reducing the force pressing the passenger into the seat.
Bremsstrahlung produced by a high-energy electron deflected in the electric field of an atomic nucleus. In particle physics, bremsstrahlung / ˈ b r ɛ m ʃ t r ɑː l ə ŋ / [1] (German pronunciation: [ˈbʁɛms.ʃtʁaːlʊŋ] ⓘ; from German bremsen ' to brake ' and Strahlung ' radiation ') is electromagnetic radiation produced by the deceleration of a charged particle when deflected by ...
For the middle of the journey the ship's speed will be roughly the speed of light, and it will slow down again to zero over a year at the end of the journey. As a rule of thumb, for a constant acceleration at 1 g (Earth gravity), the journey time, as measured on Earth, will be the distance in light years to the destination, plus 1 year. This ...

In the classical central-force problem of classical mechanics, some potential energy functions () produce motions or orbits that can be expressed in terms of well-known functions, such as the trigonometric functions and elliptic functions. This article describes these functions and the corresponding solutions for the orbits.
