A bird flies off of a cliff, dropping a feather and knocking
ocks off the cliff. The rocks reach the ground much
aster than the feather.
Which energy transformations occur in this case?
Check all that apply.
All of the rocks' potential energy is converted into
kinetic energy because rocks do not experience wind
resistance.
Some of the potential energy of the feather is
converted into kinetic energy.
All of the feathef's potential energy is converted into
thermal energy due to the friction of air resistance.
Some of the rocks' potential energy is converted into
thermal energy due to the friction of air resistance.
Some of the feather's potential energy is converted
into thermal energy due to the friction of air resistance.
