Some benchmarks that i completed was 1.construct a loop, 2.determine dissipated energy on task,3.determine initial height to make it over a hill,4.Design sketch,5.build roller coaster prototype ,and 6.build final roller coaster. This benchmark helped me learn that when ever diss. energy starts it would never end. I also learned that the at at-bats helped me with the previous at bats and with my performance task this helped me understand that there will always be gravity in the beginning and when it goes up it gains kinetic, gravity, and diss. when it lands it has more diss and less kinetic and gravity

## Collision Deliver Blog

Identify and copy/paste the equation in your code that determines the velocity of the object after the collision. NewV1=-10

Explain how your equation uses conservation of momentum./

NewV2=(m1*v1+m2*v2-newV1)/m2;

These show the after the collision because it states that those ate the new velocity which is “NewV.” This equation shows conservation of momentum because the momentum is the same as the before and after you could find this by using the equation p=m*v. The project contains two objects,a model board and the link to the sketch pad.

Describe your process for revising and developing your collision model, including at least one example of something you changed or improved.

Something that i changed in my code was the size of object one because it was the same size as object 2. I also fixed the two objects because instead of them objects bouncing they used to just cross each other another thing i changed was the speed of the two objects, object 2 goes faster and bounces off object one.

How successful was your process for making your model? What will you try to improve when you do projects in the future?

I would try to fix object one so it would be able to move and also bounce off object 2. And maybe try to use explosion instead of them bouncing off each other.
