Manipulated variable: radius]]> 2019-01-07 06:11:06 UTC https://padlet.com/physicsmckl/54z3bueclw3k/wish/317741266 https://padlet.com/physicsmckl/54z3bueclw3k/wish/317741362 Measuring frequency:
I) mark a point on the disc
II) measure the time taken, T, for the disc to complete 20 rotations, using stop watch
III) find time taken for one rotation, t, by t=T/20
IV) find frequency using 1/t

2. Exert a force of F using a Newton-metre on the turntable. 
3. Allow the turntable to oscillate and calculate the time taken for the turntable to complete one ossification. 
4. Calculate the frequency of the turntable. 
5. Repeat the experiment by varying r. 
6. Measure the mass using balance.
