1. Unit 06 “ Circular Motion, Gravitation and Black Holes” Gravity in our Solar System

2. What if the Sun were replaced with a Black Hole with the same mass? Would we be pulled into it!? Earth & Sun Data F Gravity = ? m Earth = 5.97x10 24 kg m Sun = 1.99x10 30 kg r= 1.5x10 11 m Earth & Black Hole Data F Gravity = ? m Earth = 5.97x10 24 kg m Blackhole = 1.99x10 30 kg r= 1.5x10 11 m

3. No, we would not be pulled in! The gravitational force would be the same because the mass and distances are the same. We would orbit around the black hole – just like we orbit around the sun!!! We are beyond the event horizon, so we would not get pulled in. We would have to be closer, or the black hole would have to have a larger mass! What if the Sun were replaced with a Black Hole with the same mass? Would we be pulled into it!?

4. Determine the gravitational pull between the sun and the planet of your choice using the table of information below. Add three more zeros to the distance to convert it from kilometers to meters!
