Question
Which of the following represent examples of kinetic energy? Choose all that apply.Multiple select question.A spinning top.A carbon-carbon bond in a carbohydrate.A book sitting on a desk.A molecule of carbon dioxide being exhaled.
Solution
The examples of kinetic energy from the options provided are:
-
A spinning top: Kinetic energy is the energy of motion. A spinning top is in motion, therefore it has kinetic energy.
-
A molecule of carbon dioxide being exhaled: When you exhale, the molecules of carbon dioxide are moving, so they have kinetic energy.
The other two options do not represent kinetic energy:
-
A carbon-carbon bond in a carbohydrate: This is an example of potential energy, not kinetic energy. The energy is stored in the bond and can be released, but it is not currently in motion.
-
A book sitting on a desk: This is also an example of potential energy. The book has the potential to create motion if it falls off the desk, but while it is sitting still, it is not exhibiting kinetic energy.
