About This

• [Action and Reaction Trolley]- Explore the phenomenon that the wind generated by the propeller causes recoil to propel the car forward.
• [Product Structure]- A small motor and propeller are installed on a small car, plus two AA batteries (with battery clips, electric,The pool needs to be prepared by yourself), a switch and a baffle plate. The principle is to use the reaction of wind (ie recoil) to push the car forward.
• [Application]- It can intuitively and vividly enable students to understand the generation and utilization of recoil force, so as to understand the principle of the advancement of jet aircraft and rockets.
• [Ideas]- We have provided some simple experimental ideas. In our pictures, we can use this to open up our ideas to understand some hypotheses about Kinetic Potential Energy.
• [Practical Science]- Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life.
