True

False. In a collision, there is only one collision that occurs between two objects or vehicles. The impact may result in secondary collisions involving other objects or vehicles, but the initial collision involves only the two primary objects.
False. According to the law of conservation of momentum, the total momentum of the three objects before the collision must be equal to the total momentum after the collision, assuming no external forces are present.
False. In a collision between two objects, momentum is conserved but it is not necessarily distributed evenly between the objects after the collision. The total momentum before the collision should be equal to the total momentum after the collision, but individual objects may have different momenta.
