Learn more about kinetic energy using these curving conservation of energy tracks! Will the track with the steep incline produce a ball with more kinetic energy than the straight track? Line up the catching curve at the bottom of one of the tracks, roll the ball down the track and mark the height it reaches on the catching curve. Repeat this for all four tracks. Students will easily see a similarity-all four marks on the catching curve are at the same height! This activity quickly illustrates that the kinetic energy of a ball at the bottom of a track is directly related to the potential energy it had at the top. When a ball drops a certain distance, it will always have the same kinetic energy no matter what path it took to get to the bottom. An exciting test of the conservation of energy principle! Precision-cut tracks are made of durable, high-quality wood. Complete instructions are provided. A Flinn PSworks Support Stand or other support stand and clamp is required, but not included.
