<u>Answer: </u>
Balloon powered car works on the principle of Newtons III law. Escaping air from the balloon, the car accelerates forward. The reaction is the air behind the car, pushing against it, and with the same force car moves forward is the action.
<em>Some scientific questions are:</em>
1. What is the energy stored in the balloon?
Ans: Potential energy (Potential energy is stored in elastic balloon)
2. Which energy is used in balloon-powered car?
Ans: Kinetic energy. (Whenever the balloon escapes the air, potential energy is converted into Kinetic energy)
3. What is the principle involved in balloon powered car?
Ans: Newtons III law.
I believe the answer is hertz.
