It would fly and roll much farther than if it were thrown in earth's atmosphere due to reduced friction caused by the lack of air.
travel horizontally
If there was no gravity, the ball would not fall back down to the ground after being thrown. It would continue in a straight line with the same speed and direction it was thrown with until it was affected by another force.
The ball follows a parabolic path when thrown. In a vacuum (with no air or other forces acting upon it) the gravitational pull of the earth causes the ball to accelerate toward the earth (9.8m/sec
If the height from which the ball is thrown is increased, the time of flight of the ball would increase as well. This is because the initial velocity of the ball would be higher, leading to a longer time for the ball to reach the ground.
If the ball was thrown-in by a teammate, no. If the ball was thrown-in by an opponent, yes.
If the air is still, then the ball would move in a straight line, and come to a slow eventual stop due to friction with that air. If the air is moving, then the ball will slow down and eventually be moving around with the air, the amount of which would depend on the mass of the ball and the friction it has with the air. If it's in a perfect vacuum, then it will simply keep moving in a straight line at the speed that it was released at.
It would travel in a straight line until air resistance brought it to a standstill. It would then hover at that point - in mid-air forever. If air resistance is also removed from the scenario an even stranger thing will happen. The ball will continue in a straight line forever. But, because of the curvature of the earth, the earth's surface will drop away so that the ball will actually fly off into space. One problem with this thought experiment is that the concept of a "straight" line depends on gravity.
YES ... this would be the same as if it was thrown and it the foul side walls ...
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
If it's a ball like a tennis ball, an old ball would be smoother and would have less drag.
The ball thrown straight down from a bridge will experience an acceleration due to gravity. On Earth, this acceleration is approximately 9.81 m/s^2 and acts in the downward direction. The acceleration will cause the ball to increase in speed as it falls towards the ground.
Yes, a runner is out if hit by a thrown ball while running the bases.
