Science Kids: Physics of Rockets

The video tutorial explores the physics of rockets, focusing on Newton's laws of motion and their application in rocket design and launch. It covers the concepts of thrust, weight, and air resistance, and explains how rockets are controlled and stabilized. The engineering design process is discussed, highlighting the iterative nature of designing rockets and the importance of teamwork. The video also touches on the technologies enabled by rockets, such as GPS.
