hi guys
so i have to build a transformer for physics which demonstrates 5 types of energy transformations
im using a pulley to put spring on  one side and mass on the other side
so tht when the mass drops the spring on the other side is stretched
but its not working right
and below the bucket of mass i want to attack a magnet so it attracts the magnet below
but its going all crazzy
any ideas on how to secure the spring properly and how to make the pully go smoothe (the thread)
also i wud really appreciate if anyone can help me with projectile motion (launching the marble)
i was thinking of using the spoon but my teacher said dont it will get complicated
so any other ideas for the launch? tht will take less space and work efficiently
thanks again!
