Kinetic energy is the energy of the motion.
This is because the kinetic energy can be calculated by using the formula,
K.E.=1/2 mv^2
where, v is the velocity of moving body i.e. the body is in motion.
The answer is Nuclear Fusion. The sun emits energy by converting hydrogen into helium. Nuclear fusion does two things, it converts hydrogen into helium and it also converts mass to energy.
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.
When a substance is heated, the molecules begin to vibrate faster and the space between molecules increases. So it would be speeding up.
