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 - correct answer 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 proport...
