Doc Brown's GCSE OCR 21st Century Science-Physics Revision Notes

PLEASE NOTE NEW revision summaries for the NEW OCR 21st Century Science B GCSE Physics B and NEW OCR GCSE 21st Century Combined Science B Physics courses: Revision for Chapters P1-3 and  Chapters P4-6 STARTING with Y10 in Sept. 2016 onwards, first exams in 2018

OCR GCSE 21st Century Science Physics Module P7 Further Physics – Studying the Universe

P7.1 Naked eye astronomy

  • 1. know that the Sun appears to travel east-west across the sky once every 24 hours, that the stars appear to travel east-west across the sky once in a very slightly shorter time period, and that the Moon appears to travel east-west across the sky once in a slightly longer time period

  • 2. HT only: Be able to explain why a sidereal day, a rotation of 360° of the Earth, is different from a solar day due to the orbital movement of the Earth and that a sidereal day is 4 minutes less than a solar day

  • 3. understand that the planets Mercury, Venus, Mars, Jupiter and Saturn can be seen with the naked-eye and that all the planets appear to move with the stars but also to change their position relative to the fixed stars

  • 4. Be able to explain the apparent motions of the Sun, stars, Moon and planets (HT only) in terms of rotation of the Earth and the orbits of the Earth, Moon and planets (HT only)

  • 5. Be able to explain the phases of the Moon in terms of the relative positions of the Sun, Moon and Earth

  • 6. Be able to explain both solar and lunar eclipses in terms of the positions of the Sun and Moon and explain (HT only) the low frequency of eclipses in terms of the relative tilt of the orbits of the Moon about the Earth and the Earth about the Sun

  • 7. Be able to explain why different stars are seen in the night sky at different times of the year, in terms of the movement of the Earth round the Sun

  • 8. know that, and explain (HT only) why, planets sometimes appear to move with retrograde motion relative to the ‘fixed’ stars

  • 9. understand that the positions of astronomical objects are described in terms of two angles (eg right ascension and declination) and (HT only) understand how the angles relate to the celestial sphere.
