Trip to Busch Gardens and a lesson on Physics!

We had a wonderful time at Busch Gardens past weekend. My kids enjoy the rides and as they are now a little older want to try out the roller coasters. Great teaching moment to talk to kids about the laws of physics. What makes the roller coasters move so fast? How do they gain so much energy? Talk about momentum and why roller coasters move in loops. How do cable cars move? Of course refrain from giving a long lecture on the laws of physics but show them simple examples and kids will grasp the information right away.
