The Moving Center of Mass of a Leaking Bob
P. Arun
The evaluation of variation in oscillation time period of a simple pendulum as its mass varies proves a rich source of discussion in a physics class-room, overcoming erroneous noti…
Studying Three Phase Supply in School
Amit Kumar Singhal, P. Arun
The power distribution of nearly all major countries have accepted 3-phase distribution as a standard. With increasing power requirements of instrumentation today even a small phys…
Reaction Time of a Group of Physics Students
Charu Saxena, Rini Kaur, P. Arun
The reaction time of a group of students majoring in Physics is reported here. Strong co-relation between fatigue, reaction time and performance have been seen and may be useful fo…
Study of the Damped Pendulum
Akhil Arora, Rahul Rawat, Sampreet Kaur +1
Experiments on the oscillatory motion of a suspended bar magnet throws light on the damping effects acting on the pendulum. The viscous drag offered by air was found the be the mai…
An accurate formula for the period of a simple pendulum oscillating beyond the small-angle regime
F M S Lima, P Arun
A simple approximation formula is derived here for the dependence of the period of a simple pendulum on amplitude that only requires a pocket calculator and furnishes an error of l…
Simple 8085 microprocessor compatible I/O card
Arti Dwivedi, P. Arun
A simple interfacing project with the 8085-microprocessor kits available in under graduate college labs has been discussed. The interface card to study the I-V characteristics of a…
