On Tuesday we had a long class, which was an hour and thirty minutes. At the beginning of the class we got our blog rubrics back to see how well we did on our comment. We discussed our 7th grade blog, as well as the 8th graders blog. When we were finished discussing about the blogs, we then talked about SCIENCE DAY! Science day will be this Thursday, tomorrow, and there will be viewers all the way from teachers, to our parents friends coming. We will show our viewers some of the labs we worked on this past school year, including the lab we just did, the Balloon Rocket Challenge. On Tuesdays class we also talked about a new topic, to us, and it is called Momentum. We discussed Momentum, the Conservation of Momentum, the Collisions With Two Moving Objects, One Moving Object, and With Connected Objects.
- Momentum: is a characteristic of a moving object that is related to the mass and the velocity of the object.
- Momentum=Mass *(times) Velocity or P=M *(times) V
- More Mass= More Momentum
- More Velocity= More Momentum
- Momentum may be transferred from one object to another, but is not changed!
- Conservation of Momentum states that, in the absence of outside forces, the total momentum of objects does not change. The amount of momentum is the same before and after they interact.
- Collisions With Two Moving Objects= The impact of two moving objects
- Collisions With One Moving Object= The impact with one moving object
- Collisions With Connected Objects= The impact of connected objects
