Aim: To investigate how to make a cotton reel car move, using potential energy. Keywords: Elastic potential energy How cotton reel cars work most efficient:
When using the cotton reel cars our team realised that the tighter we wound the rubber band, The longer and faster the car moved. But there was a tipping point where if you wound it too far it would tip over and stand instead of rolling. This is because the tighter wound the rubber band is, the more elastic potential energy is stored ready for use. Lesson Summary: In today's lesson our group learnt:
