WebWhen the planet is closest to the Sun, speed v v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases. At all points in the orbit, angular momentum and energy are conserved. WebE m e r s o n and Rabinowitch (1960) discovered that the- far-red radiation could increase the evolution of oxygen from water. T h e far-red region of X > 0.7 p.
