Media Work

Today we searched and found a video that we may be using for calculating the Centripetal Force...

Also, we began to apply the idea of Centripetal Force to this video, and how it would work.

 

We will be meeting out of class to calculate the Centripetal Force and make a presentation, then finish up our posterboard and media presentation.

Being Productive

Today we made plans for our layout of the multimedia presentation, the trifold poster board, and physical model. We have begun our process for printing and  setting things up.
All and all a very productive day!

Angular Momentum

Angular Momentum is equal to the product of mass, velocity, and distance from mass to axis rotation. Another equation for angular momentum is the moment of inertia multiplied by the angular velocity. Angular momentum is not gained or lost from the time the gymnasts pushes off the mat. However, gymnasts are able to change their rate of rotation. They do this by changing their center mass of pulling in their arms or vice versa to perform tricks without pushing off of anything.
