If the Earth's axis were 'straight' ... pefectly perpendicular to the ecliptic
plane ... then:
-- Day and night would be the same length ... every day of the year,
everywhere on Earth !
-- There wouldn't be any seasons, anywhere. There might still be some
'weather' ... cloudy days, sunny days, occasional rain, wind etc. But
there would be no average change during the year. No hot months or
cold months. In any one place, the weather would always be generally
the same, every day, all year. Everywhere all around the equator would be
generally the hottest on Earth, and the local climates would generally get
cooler as you moved away from the equator and toward the poles.
To answer this question, it helps enormously if you know
the formula for momentum:
Momentum = (mass) x (speed) .
Looking at the formula, you can see that momentum is directly
proportional to speed. So if speed doubles, so does momentum.
If the car's momentum is 20,000 kg-m/s now, then after its speed
doubles, its momentum has also doubled, to 40,000 kg-m/s.
Answer:
We answer that before but I forgot
Answer:
Well, it has to do something with the force of the train. It's pulling you, a force of gravity
However jumping off results in a different sort of energy, the train know is moving farther away as you jump down. So you end up in a different place
