- 1. Multiple ChoiceThe definition of gravitational field strength is:The region of space surrounding a body where other bodies will feel an attractive force due to it.The region of space surrounding a body where other bodies will feel an repulsive force due to it.The region of space surrounding a charge where other charges will feel an attractive force due to it.The region of space surrounding a charge where other charges will feel an repulsive force due to it.
- 2. Multiple ChoiceThe closer together the gravitational field lines.....the weaker the gravitational field strengththe stronger the gravitational field strengththe more repulsive the gravitational field strength
- 3. Multiple ChoiceHow far out from a mass should the gravitational field lines go....to where the gravitational field becomes negligableto twice the diameter of the massinfinitely farto four times the diameter of the mass
- 4. Multiple Choice
In this equation...G is the gravitational field strengthr is the distance between the 2 massesF is the repulsive gravitational forcem is the momentum of the mass - 5. Multiple ChoiceThe gravitational field strength of Earth is...uniform far away from the surface and radial close to the surfaceuniform close to the surface and radial far away from the surface
- 6. Multiple ChoiceKepler's third law states that....An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies)
