Unformatted text preview: Sean Daehn Collision Lab Report
Spr ingy St icky PsB PsA Purpose: to develop a conceptual and mathematical model for a two or more particle collision with an isolated system. Apparatus: Procedure: On the first day, we did the sticky collision. We had one car at rest and one car that collided in to the one at rest then, they stuck together. We had the motion sensors that calculated the speed before and after the collision. On day two, we did a springy collision or elastic. We had a still car then got one moving and it went towards the other car and made it move without touching it. We also used motion sensors to find out the speed before and after the collision.

If a moving car has a force of three when it collides with another object the system will still have a total force of three. That is what opposites are. The transfer of momentum is when an object collides with another and the object that was originally moving stops or slows down and the object that was still begins to move. Like the springy collisions we did. The system momentum is constant or conserved. That means that no matter what the system momentum started out as it will always remain the same in some form so if it is six before it will be six after. ...
