a bird flies off of a cliff, dropping a feather and knocking rocks off the cliff. the rocks reach the ground much faster 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 feathers 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 feathers potential energy is converted into thermal energy due to the friction of air resistance.

Answer

Brief Explanations:

In reality, both rocks and feathers experience air - resistance. Potential energy of an object at a height is converted into kinetic energy as it falls and some into thermal energy due to air - resistance. Rocks don't convert all potential energy to kinetic as they have air - resistance too. Feathers convert some potential energy to kinetic and some to thermal due to air - resistance.

Answer:

Some of the potential energy of the feather is converted into kinetic energy. 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.
