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) of the body you are bound to, and INVERSELY proportional to the SQUARE of your distance (r) from its center mass," or g = m / (r * r) - It would be four times stronger What did newton's law of universal gravitation tell us about how gravity works? Hint: Recall that the FORCE of gravity ('F = ma' or 'F = mg'), unlike gravitational acceleration (just the 'a' or 'g'), depends on the masses of two objects interacting -- remember that the 'g' in 'F = mg' is also dependent on a mass value (of a second object). - The force of gravity from the sun will be stronger on an object with more mass
