Forces, Forces, Everywhere!

s and gymnasticsGravity is always 'on'...you don't need to check.  :D

We have been talking about the various forces and Newton's Three Laws:

1. Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
   
   
2. Force equals mass times acceleration [  ].
   
   
3. For every action there is an equal and opposite reaction.
   
   

Some of these laws can be explained in the following videos where ballet, gymnastics, and roller coasters are closely examined through a lens of science and forces.
