TPJ Jaime Valverde 11/25/08 We first went over the unit four test which was on Newton's second law. We started a new unit it was on Newton’s third law. First we had to predict what was going to happen when two cars collide. We had to predict what car would receive the greater amount of force, because he would change the mass and velocity for every collision being tested. I predicted that they would receive the same amount of force for each test no matter what velocity or mass would be. he also tried to put extra inertia by putting sand paper but it still didn't matter both of them received the same force. My predictions were all right because I learned this last year in APS. And I also learned that if two objects hit each other they would receive the same force. Mass of car A is: 100N Mass of car B is: 50N

“which one would receive the greater amount of force?” “oh yeah, Newton’s 3rd law they would receive the same amount of force”
