Physics Dance

Last week on wednesday we danced for our physics class. First it was fun but, then when Mr. José Popoff  told us that we had to do a blogpost I didn't like the idea. Know I wrote this post to see how the three laws of motion of Newton apply for dancing.

1. First Law of Motion: An object at rest will remain at rest unless acted on by an external force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.


We applied this force when we were waitng in the pad for the song to start, so we are at rest and will continue at rest unless an external force affects you.

2.Secon Law of Motion: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). F=ma

We applied this when we move our feet, because a fat person will need more force to move his feet than a thin person.

3. Third Law of Motion: For every action there is an equal and opposite re-action.

This one applies when step on one of the arrows and then it is reflected in the game that you touch that arrow, or when you jump you have to come down again because the earth pulls you down. This is like saying "you can touch without being touched".

I hope you like my post and now you can see Mr. JP dancing.
