Items associated with this NGSS statement in this project (ASPECt) and other key ideas
RG159002	When one car hits another car and the speed of the cars changes, the change in speed is a sign that energy was transferred.
RG096002	After one ball collides with another, the first ball moves slower.
RG097002	After one ball collides with another, the first ball moves slower because it transferred energy to the second ball when the balls hit each other.
RG095002	Energy is transferred between two balls as the balls hit each other.
RG098002	After Cart A hits Cart B, Cart A is going slower and Cart B is going faster.
RG099002	After one car bumps into another car, the first car moves slower and second car moves faster because energy was transferred from the first car to the second..
