It's exactly that. The rotational motion apparatus is connected to the computer which measures angular acceleration and the final angular velocity. I used v = r##\omega## to calculate linear final velocity and a = r ##\alpha## to calculate linear acceleration. I used the linear acceleration to...

Ah yes. There's the rotational motion apparatus with three spindles of different radiuses. The wire is wound on at say the smallest size spindle and it is let go. It stop when the hanger which is connected to the wire hits the ground. I calculated my KE(final) by adding KE(rot) =...

Homework Statement I am doing the rotational motion experiment with a rotary disk that has three spindle sizes. A string goes around the spindle and is connected to a hanger. I calculated my ratio as a percentage of total final KE to decrease in potential energy and it comes out to be around...
