Which statement about gravity is always true? a. the force of gravity between two objects is greater when the objects have less charge and are closer together. b. the force of gravity between two objects is greater when the objects are farther apart and have more mass. c. the force of gravity between two objects is greater when the objects have less mass and are farther apart. d. the force of gravity between two objects is greater when the objects are closer together and have moremass.

The answer is c because the farther apart they are the greater there gravity is

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
