2/16 Williams

Thursday was a fairly basic workday. We spent the entire class getting ready for the premiere of Sphere Cow's Flight!, and for all the other crazy coasters as well. 

QUESTION OF THE DAY!!

To find the exit velocity with the photogate, we used the times that the photo gate recorded, and then used the diameter of the marble as the distance, and thus had distance and time making velocity easy to find. To find the exit velocity using the table, we measured the height to the exit and how far from the table the marble landed, then using those 2 numbers and the 3rd kinematics equation found the time, giving us time and distance, allowing us to find the exit velocity.
