Year 12 Mechanics Conservation of Energy Experiment:
Purpose:
The purpose of this experiment is to demonstrate the conservation of energy using a large mass on the end of a string.
Equipment:
String, rope etc.
Large mass / ball etc.
Support hook with open space.
Method:
Connect a large mass, via a string (rope) to a secure hook.
Get a student to hold the mass against their cheek
Ask student to stay perfectly still
Mass will come back to the exact same starting place
Pitfalls / causes of error
Caution should be used if the center of mass of the object being used is not in the center of the object. I once used a 5kg slotted mass which was released side on, and then returned front on. The center of mass returned to the same position, but due to the non-symmetrical nature the mass hit the student..... it does not make for a good demo!
