A thorough breakdown on the process’ that produce light and lights existence and behavior in nature.
SciShow Space takes you into Low Earth Orbit to explain how artificial satellites get up there and stay there — at least for a while.
Open the embedded graph to change the value of h and calculate the gravitational potential energy / kg at different heights. Can you estimate the kinetic energy needed to escape the Earth’s gravitational field?
Investigate the value of g (m/s2) varying with distance (km) from the centre of the Earth.
