If air resistance is taken into account, the ball would continue moving in a horizontal direction, slowing as it went and then stop - suspended in mid air.
If there were no air resistance, the ball would continue to move in a straight line for ever. However, the surface of the earth would curve downwards (because it is a sphere) and so, relative to the earth, the ball would fly off at a tangent into space.
Of course, all this begs the question as to why the person who threw the ball did not fly off onto space long before throwing the ball!
travel horizontally
Gravity doesn't make a pendulum stop. Air resistance and friction in the pivot are the things that rob its energy. If you could eliminate those and leave it all up to gravity, the pendulum would never stop.
Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.
Yes, there can be negative gravity. If a gravity is a pulling force then in the other hands a negative gravity would be a pushing force, in other words, the negative gravity would push us to wherever and the positive gravity on Earth would pull us.
There are just two ways to get the value of 11 when dice are thrown. one would be a 5 and 6 and the other is a 6 and 5.
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.
No, Earth's gravity would not affect Pluto. However, the suns gravity does.
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.
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.
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.
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.
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?
because there is no gravity
They would not affect Newton's laws in the slightest.
