Gravity - all things fall with the same acceleration?

Here we have a video highlighting the importance of considering all aspects of the situation before saying rote-learned statements. Many students may say “all things fall with the same acceleration” and feel somewhat pleased with themselves that they remembered to say acceleration and not velocity. This video demonstrates that it is the centre of mass of a freely falling object that has the value of the local acceleration due to gravity and sometimes this causes other parts of the object to accelerate faster than “g”. 

For the student therefore this is an exercise in understanding the precision of the discipline base language and the depth of knowledge that underpins it.
