Today in class we started off with a daily question that where we were supposed to figure out the difference between a lazy susan and a regular lunch cart. The difference was that the lazy suzan was spinning and the cart moved in a linear motion usually. The cart can also spin, but in only 2 directions, clockwise and counter clockwise.

Afterwards, we used the knex merrigoround to make an equation to figure out the tagential speed. The speed was very slow because of the speed and of the radius. If the radius is small, the speed is small, and if the radius is larger, the speed is much greater. The direction is also inversely proportionate.

We can also do the calculations by using one unit of measure and counting the rotations in the amount of time. These calculations gave us the frequency. We learned that T=1/f which are inverses of each other.

We watched a video on a ride called the claw, and then looked at the data sent to Mr Manning from Hershey park. We were then supposed to calculate the tangential speed for the ride, which was on page 3 of the packet. //**
