Fast STop Cars
This challenge is requiring gravity to power a car. gravity and some form of a 2kg maximum weight. It also requires the car to stop at a specified distance, which will only be announced the day before the challenge, which means the students must have a way to calibrate and force the car to stop. there are no material restrictions and how you convert the GPE of a 2kg weight 1m highKE is up to the students.
This paper is slightly different from other papers. the other papers have referenced the thinking process as being iterative between challenges but still focus on the current challenge. in this paper the students will focus on the journey from the very first marshmallow challenge all the way through to the current challenge.
