5 . Chair Physics or Why Heads Will Roll!!!!

February 4, 2011

Teachers hate kids leaning back on chairs for a good reason.

They may not lose their head, but they could lose a few brain cells if they fall. It’s all to do with angles, but I suggest you use an empty chair or, if you like Myth Busters, perhaps you could use a dummy.


This is not a dummy.


The Centre of Gravity rules for stability apply to a person sitting in a chair is the same way the rules apply to a kid with a backpack.

For more information this is a cool GCSE Physics link using Batman and Centre of Gravity.



This is a really cool school chair trick. The image may not appear on your iPad.

This is just a really cool chair.
