− | + | Angular momentum is the force upon an object having a certain velocity while spinning. You may remember the certain strain when a spinning yoyo returned into your hand, giving it that much "slip" to discomfort you. The energy of that momentum does that. Angular momentum is also forced upon the Earth, as it is spinning 24 hours a day, 7 days a week. This 24/7 rotation enables us to have a clock. We say that the Earth is running "clockwise". But viewed from the north of the {{w|ecliptic}}, the Earth in fact turns counter-clockwise. | |
− | [[Megan]] is | + | Nevertheless, [[Megan]] tries to work against this (massive) energy. She is spinning counter-clockwise, trying to generate energy to reduce the Earth's moving. Her move will force the Earth to slow down clockwise, but a stick figure just does not have the mass for a measurable effect. So, it's obvious that she will not be able to alter the turn of the Earth. But the romance part is also obvious, who wouldn't want to be longer with the one they truly love? |
− | + | [[Randall]] states the obvious in the title text: While not being able to reverse time, enjoy your night time. Sunrise always comes too early. | |
