Week 13 physics

The first fay i was not present for the class because i attended challenge day. But on the second day we did this lab with this car on a low friction lab and the ramp at a downward slant. We where trying to find the velocity for this car i she lets it slide down the ramp and we worked with the smart board to calculate everything we needed. We did this as a class so if you where falling along then we would all be on the same page. What we did on thursday find the definition of acceleration. To find the acceleration of something we went to the roof so we could drop things off of it. People brought in old technology so we could drop them we drop one phone we thought it would break but it didn't. The reason for this was so we can find all of the things we need for tomorrow. The next day, the last day we made a Equation for everything we found out yesterday we did all of this to find the acceleration of the objects.
