According to Newton's Second Law of motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? Hint: Remember F = m * a - Acceleration Increases If the earth were moved to half its current distance from the sun, how would the force of gravity by the sun on the earth change? Hint: Recall the form of the equation that you derived, earlier in the game: "gravitational acceleration (g) is proportional to the mass (m...

We have learned that the centre of the milky way contains a very massive black hole. We developed this understanding by: - Monitoring the orbital motions of many individual stars in the very central parts of the Milky Way If the sun were to be squashed down small enough to become a black hole, then: - The planets in the solar system would orbit the Sun in unchanged fashion (but would receive no light from it) The first stellar mass black hole identified, Cygnus X-1, was found in 1973. The n...
