Physics of Roller Coasters (24:55)
Learn the basic physics concepts that keep you in your roller-coaster cart and your cart on the track through the death-defying plunges and hairpin turns. What is the difference between speed and velocity? What is the formula for Gravitational Potential Energy? What is the Law of Conservation of Energy? What is friction? What is acceleration? How do you engineer a roller coaster? The answers to all of these questions and more are covered in depth with detailed graphics, diagrams and exciting video. On-screen, multiple-choice reviews at the end of each segment reinforce important concepts and make learning fun.

Physics of Rockets (21:36)
Learn all about how rockets work. What are Newton's Three Laws of Motion? Why are thrust, weight and control important to rocketry? How do you design a rocket? What is triangulation? How can engineers determine the exact position of a rocket? The answers to these questions and more are covered in depth with detailed graphics and exciting video. On-screen, multiple-choice reviews at the end of each segment reinforce important concepts and make learning fun.

Swings, Slides, and Science
Did you know that when you’re soaring on the swings, or sliding down the slide, you’re taking part in some seriously cool science? Jessi explains the forces you can find at the playground!

Forces and Motion – Magnitude and Direction
Next Generation Science - Forces are what make things move. You can think of a force as a push or a pull. A push is when you apply force to move something away from you. A pull is when you apply force to bring something closer to you.

Forces in the Playground
Next Generation Science - Today, we're visiting a place familiar to all of us - a playground. It's not just a place of fun and laughter; it's also a fantastic real-world setting to explore and understand the concepts of force and motion.

Science Buddies - Push and Pull
Your kindergarten students are used to moving objects. They throw balls, play with toy cars, and sweep the floor, but how much do they think about these actions? In this fun, hands-on lesson, you will use a game (rolling balls) to explore how pushing and pulling affects an object's motion. This lesson can be expanded with a second lesson exploring how objects can push each other, and how weight influences motion.
