A geometric view of the possible outcomes of elastic collisions of two massive bodies is developed that integrates laboratory, center of mass, and relative body frames in a single diagram. From these diagrams all the scattering properties of binary collisions can be obtained. The particular case of gravitational scattering by a moving massive object corresponds to the slingshot maneuver, and its maximum velocity is obtained.

The scattering angles and speeds resulting from an off-centre elastic collision of a smooth puck or sphere incident on a second one at rest on a frictionless surface are analysed in terms of the… Expand

We derive the equations for the gravity assist manoeuvre in the general 2D case without the constraints of circular planetary orbits or widely different masses as assumed by Broucke (AIAA/AAS 1988)… Expand

We aim to create deterministic collisions between orbiting bodies by applying a time-dependent external force to one or both bodies, whether the bodies are mutually repulsive, as in the two- or… Expand

In an elastic collision between two rigid bodies of arbitrary shape, the component of relative velocity of the impact points along the impulse direction is exactly reversed. The two relative velocity… Expand

We present an approach to two-body collision processes which simplifies the algebra and leads to a convenient geometrical visualization of these processes in the velocity plane. Special cases, such… Expand
