The gravity exerted by Planet X is less than the gravity exerted by Planet Y. If a ball were launched upwards on each planet with the same amount of net force, what would the difference be in the acceleration of the ball?
It will initially accelerate more on Planet X.
The gravity on Planet X is less than that on Planet Y, which means that for the same net force applied to the ball, it will experience a greater acceleration on Planet X due to the smaller gravitational pull opposing the force. According to Newton's second law, acceleration is inversely proportional to the force of gravity acting on the object.
On Planet X, the weaker gravitational force means that the net force acting on the ball results in a higher acceleration compared to Planet Y. Since the gravitational pull is less, the same net force will produce greater upward acceleration on Planet X.
This choice is incorrect because an upward force is being applied to the ball in both scenarios. The presence of a net force will cause the ball to accelerate, and it cannot remain still unless no force is acting on it, which contradicts the premise of the question.
This option is incorrect because the differing gravitational accelerations on the two planets mean that the ball will not accelerate the same. The net force divided by the mass of the ball will yield different accelerations based on the varying gravitational effects of each planet.
This choice is incorrect since Planet Y has a stronger gravitational force. The net force acting on the ball would be reduced by this stronger gravity, resulting in lower acceleration compared to Planet X, where gravity is weaker.
In summary, the initial acceleration of the ball launched on Planet X will be greater than that on Planet Y due to the lower gravitational force on Planet X. As a result, the net force applied results in a larger acceleration on Planet X, illustrating how gravitational differences influence motion under the same applied force.
