When we talked about Newton's (14) Law , we talked a little about collisions We talked about a "trick " question about a bug hitting the (15 ) of a truck and how the (16) of impact compared between them . Most people say that the (17 ) experiences the greater force but we know that for "every action there is an (18) and opposite reaction . The reason why the bug appears to experience the greater force is not because the force on it is (19) but because it has a much smaller (20 ) and so it undergoes a greater deceleration The study of (21) is just taking a closer look at the relationship between the masses and the Before collision collision After collision velocities of crashing objects O before and after they crash. There are two basic kinds of collisions . In the first kind , the collisions a perfectly (22 ) and the two objects bounce off each other with no loss of kinetic energy (in Joules ). At right you can see three kinds of (23 ) (same answer as No . 22 ) collisions . In the top Figure , after the collision , the first ball passes all of its momentum to the second ball . In the middle and bottom Figures , each ball exchanges its momentum with the other ball . In the second scenario , when the two objects collide , some of the kinetic energy turns into (24) This is called an BEFORE AFTER (25 ) collision because the m.0o kg m:DO kg bounce is not as bouncy as it could be in ideal Y=7 v.6 m/s m: 40 kg conditions . Objects in this kind of collision tend ma 40 kg Y:0 m/s to (26) to each other after the collision (see Figure at right )
