Today I could complete set-up of a mechanics experiment to study conservation of momentum. In this experiment we can determine momentum of both gliders on air track, before and after collision. Different types of collisions can also be studied.  Wrote  python code to get the data. Need to debug the errors and develop a GUI, where user can enter the values of masses of both the vehicles and get the value of momentum, which is the product of mass and velocity.

Today we could also design an instrument using  a  pulley and a photo-gate to measure acceleration. ( thanks to open educational resources for the idea..)

Tomorrow I will work on setting up of this new instrument for different experiments involving friction.
