today, I could get the apparatus for energy conservation experiment prepared from local carpenter in wood. Its working fine. Wrote python program for the experiment. User can enter the value of initial height of the metal sphere, to calculate Potential energy. When the Sphere roles between two photo-gates, time can be measured with microsecond accuracy and velocity and hence kinetic energy can be calculated. The results show that Initial Potential Energy is equal to final Kinetic Energy and hence proves the Energy Conservation Theorem.
This simple experiment is very useful for high school students.
Did required modifications in the main GUI program ” CROPLUS” written by Dr Ajith Kumar, to access these new experiments. Uploaded this program on my GIT repo.
Next week I will finalize sound experiments.
