Good program to view for different ways to approach teaching circular motion. It addresses frame of reference concerning centrifugal forces and orbits and the role of inertia and gravity in teaching these concepts. The questioning sessions used to ascertain prior knowledge were excellent.

This is a great webinar to eliminate our own preconceived notions regarding to force and motion. I really learned a lot and at first felt silly I did not get some of the answers right. Even though I watched the archive and did not participate in the live feed, the chats from the original participants helped in my gaining of knowledge in this area.

Bill Robertson does a fabulous job modeling how we should draw students into thinking about the concepts of motion and force. By engaging students in the conversation, students can work through their thinking, dispel their misconceptions, and come to a better understanding of how things move.

It always been a difficult to understand forces you cannot see but feel, one of these forces is centripetal force which is any motion in a curved path, and requires a force directed toward the center of curvature of the path. This is also referred to as "center seeking" force. With the illustrations accompanied with simple explanations, some of the concepts are a little less daunting.

Overall pretty interesting and engaging. Loved the diagrams and vocabulary clarification. I found it very interesting that the only way to get the roll of tape to move away from you is to exert a force toward your body. I thought it was away from your body. I also found it interesting that in order to make an object move in a circle is to exert a force towards the center of the circle as well as a small path along the outside of the circle. I was a little confused about the spinning ride discussion. I think the diagram needs to show the arrow that represents the force of the person to the wall. Without that arrow the person should be falling down. I thought you needed balanced forces to cancel each other out. Definitely go clarification on being weightless in outer space. I thought since you weren’t on the earth you were considered weightless. Didn’t think about the earth continuing to pull on you no matter how far you are out in space. Good clarification to the ‘weightless’ topic. Mr. Robinson made it pretty clear as to why/how the earth can orbit the Sun. I am still a little confused by the diagrams he showed. He said 1 and 3 were not correct but that 2 and 4 were. I don’t understand how 2 is accurate. The arrow is only pointing down. Again, equal forces are confusing me. I thought it had to be there or the object would move. (In this case the Earth.)
