Question

A group of Physics students is nssigned the tosk of exploring relhtionships betwetn variables when a hanging weight is supporled by a smaller weighj spinning in a cirle (like in the lab you performed). A haning nass (mz) is supported by a sccond mass (mi) spinning in a circle of radlus r I Draw free body dingrams for mand for mi. 2.Write Newton's equation form and for m. You will he using Excel or some other sprend sheel progm for this. 3, the firs experimenl, r is varied and m is spun around 10 times and he time is recorded. The two masses are kept constant Calculate the period (T) for each and record in the table. Calculate the velocity (v) for each and record in the table. Plot the data in such a way that a straight line results (use Newton's equation from #2 above). Calculate the slopc of tha lne nnd use it lo cniculate g, the acceleralion due to gravity 4. In the second experiment, m, s varied and r and m2 are kept consianı. Repeat what you did for #3. 5. ln the third experiment, m, is varied and rand 뀌」are kept constnn. Repeat whal you did for #3.
