∙ 7y agoIt 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.

If gravity did not affect the path of a horizontally thrown ball, the ball would continue to move in a straight line at a constant speed. Gravity's effect would only come into play if the ball were thrown at an angle relative to the ground.
If gravity did not affect a horizontally thrown ball, it would travel in a straight line horizontally at a constant velocity. Gravity only acts vertically, causing the ball to fall towards the ground, so without this vertical force, the horizontal motion would remain unaffected.
It is incorrect to say that if a root is placed horizontally it will bend towards gravity because roots exhibit positive gravitropism, meaning they grow downwards in response to gravity. Thus, a horizontal root would still grow downwards due to gravitropism.
How does the force of gravity affect an object's motion? What factors determine the speed of sound in a given medium? How does the angle of incidence affect the reflection of light off a surface? How does the design of a sail affect the propulsion of a sailboat?
The object will have the same acceleration of 9.8 meters per second squared whether you drop it or throw it downward. The initial velocity from throwing it will affect its overall velocity as it falls, but the acceleration due to gravity remains constant.
The velocity of a ball thrown upward at 16 ft/sec would be 16 ft/sec when it leaves the hand, but it will decrease due to gravity as it moves upward.
travel horizontally
If gravity did not affect a horizontally thrown ball, it would travel in a straight line horizontally at a constant velocity. Gravity only acts vertically, causing the ball to fall towards the ground, so without this vertical force, the horizontal motion would remain unaffected.
It doesn't matter whether the object is thrown down, up, horizontally, or diagonally. Once it leaves the thrower's hand, it is accelerated downward by an amount equal to acceleration of gravity on the planet where this is all happening. On Earth, if you throw an object horizontally, it accelerates downward at the rate of 9.8 meters per second2 ... just as it would if you simply dropped it. Whether it's dropped or thrown horizontally, it hits the ground at the same time.
It depends on the surface on which the object is moving, and also any other forces - such as gravity.
The ball would continue straight without any gravitational forces acting on it, and without air resistance. If you consider air resistance, then the spin of the ball may give it a curved path, and eventually the ball would stop traveling as the air resistance slows down the ball.
If you electrophoresed DNA vertically, you would have to account for gravity.
No, Earth's gravity would not affect Pluto. However, the suns gravity does.
The gravity on Mars is about 38% that of Earth's, so a spacecraft attempting to land on Mars would experience a weaker gravitational pull than it would on Earth. This would result in a slower descent and require less thrust to slow down for a safe landing. However, the thin atmosphere on Mars provides less resistance, making it a challenge to slow down the spacecraft effectively before touchdown.
It would just fall to the floor due to gravity.
The lower gravity on the Moon would allow the baseball to reach a higher altitude before falling back down compared to Venus, which has stronger gravity. Gravity on Venus is about 91% of Earth's gravity, while on the Moon it is about 16.5% of Earth's gravity, so the baseball on the Moon would experience less downward force and go higher when thrown with the same velocity.
because of 0 gravity
If the Earth didn't have gravity, we would be floating in the air and nothing would be in its place.
