Another modeling of this event comes from the double ball drop.
Spacecraft using the gravity-assist or slingshot method are making use of a form of this event without contact. A different form of this event occurs in the modeling of a ballistic pendulum. Another modeling of this event comes from the double ball drop. These situations include events in which two objects remain (*) separate and those in which objects stick together, known as elastic and inelastic. For 10 points, name this event generally modeled by two spheres with different momentums or directions hitting one another.
