Detailed explanation-1: -When the ball is thrown up, negative force of gravity is applied and so the speed becomes zero. After that due to gravitational force the ball falls down with same initial velocity.
Detailed explanation-2: -g on the Earth is equal to 9.8 m/s^2 while g on the moon is equal to 1.6m/s^2, so the maximum height would be the ratio of these numbers, or approximately 6. So the same ball thrown on the Earth and Moon will go about 6 times higher on the moon.
Detailed explanation-3: -Prediction: If you throw the ball hard enough, it will never hit the ground and continue to follow a stable path around the earth. This path is called an orbit.
Detailed explanation-4: -For example, when a ball is thrown up in the air, the ball’s velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.
