Newton's first law!!
I guess I never thought that things like a car accident could be related to science. This onetime, back in 8th grade, my sister was driving me to wrestling practice and we hit a tree. The airbags went off and everything turned out alright, but we both had some serious whiplash! That demonstrates inertia! Our head was still going about 45 MPH and all of sudden the car stopped, but my head wanted to keep going forward! This is a web page about whiplash. I also found this site that had games on it that you flew a space ship around. I guess it is inertia!

(Teacher) Excellent blog entry! Do you think that the force the car exerted on the tree was equal/more/less than the force the tree exerted on the car? Give me your best guess, and in the next few classes, we'll see if you were right!
(Student) I would say that the tree exerted much more force on the car, because it didn't even move! I'm not sure if that's the right answer because it seems too easy, but I don't know why it wouldn't be.
