Welcome back!

Hello everyone, it's Allyson.

I hope everyone had a well rested and fun spring break. I sure did. But now it's back to school and it's time to pull up our socks because grad is just around the corner. =(

Anyways in class today we did a lab on Centripetal Force. We timed how long it took for a rubber stopper tied to 0.8 m of string from a rod to go through 30 revolutions while spinning it above our heads. The velocity must be constant at all times to have accurate results. We also added 5 washers after each trial to add weight and to see how the results have changed.

We needed:

• to calculate the time for 1 revolution
• speed (m/s), and
• speed^2 (m's)^2

There are two graphs needed to be handed in; force vs speed and force vs. speed^2 along with the questions attached to the back of the worksheet. The lab write up is due tomorrow, so if you weren't in class today be sure to pick them up.

Take care, see you all tomorrow.
