Work done by the Sun on the Earth
Classical Mechanics
Level
2
The Earth takes 1 year to complete its orbit around the Sun. Treating the orbit as perfectly circular, find the net work done on the Earth by the Sun in \(\frac14\) of a year. Give your answer to three significant figures.
Assumptions:
Mass of the Earth = \(5.97\times 10^{24} \text{kg}\)
Distance from Sun to Earth = \(1.50\times 10^{11} \text{m}\)
1 Earth year = 365 Earth days
1 Earth day = 24 hours
