 03:40: Gravitational potential energy gets converted to kinetic energy in the fall and then back to exactly the same amount of potential energy in the rise.
 06:25: ... we're actually including the entire ballEarth system when we add in gravitational potential energy, because that energy is stored in the Earth's gravitational ...


20170816: Extraterrestrial Superstorms
 04:37: As they contract, gas giants convert gravitational potential energy into heat, which in turn powers the largest storms in the solar system.

20160413: Will the Universe Expand Forever?
 05:17: It reflects the same balance between kinetic and gravitational potential energy that we saw in our rising apple.
 05:53: So this second piece represents the capacity of the universe to slow itself down and is analogous to the gravitational potential energy.


20150527: Habitable Exoplanets Debunked!
 06:50: If everyone on Earth picked up a hammer at the same time, by how much would Earth's mass increase due to the excess gravitational potential energy?
