Why does newton's first law of motion not work on earth?
It sure works on Earth. It works everywhere. If there is no net force on an object, the object will not accelerate. Vice versa, if the object does not accelerate, that means there is no net force on the object.
Why is sputnik 1 famous?
It was the first artificial (manmade) object to be placed in orbit around the earth. It started the space race between the USA and the USSR.
How are Near Earth Object's stopped from hitting Earth?
First, the danger must be detected way ahead of time. Second, something would have to be done to change their orbits. For example, making atom bombs explode on or near their surface has been considered. If detected way in advance, a small change in its direction could take it away from Earth. This is all hypothetical - so far, no Near Earth Object has been thus stopped.
What was the first space mission to orbit any celestial body other than the earth?
The first spacecraft to orbit any other celestial object was the Soviet Luna probe, which took the first-ever photos of the far side of the Moon.
Do objects become lighter as they get closer to the center of the earth?
Objects masses would not change, but the pull of gravity on an object from another object when the first is inside the other is effectively zero when the inside is at the center of mass of the outer. If the Earth were a thick walled but hollow sphere, objects would stick (weakly) to the inside surface as well as the outer.
What was the first satellite called?
The Sputnik program was a series of robotic spacecraft missions launched by the Soviet Union. The first of these, Sputnik 1, launched the first human-made object to orbit the Earth.
What is the measurement of the force of gravity pulling an object toward the earth?
The strength of the gravitational forces between the Earth and an object on or near it is called the "weight" of the object. In reality, there are two equal and opposite forces going on. The Earth attracts the object toward it, with a force that is the weight of the object on Earth. At the same time, the object attracts the Earth toward it, with a force that is the weight of the Earth on the object. The forces are equal. When the object is our body, we obsess about the first one. Nobody ever talks about the second one.

Why and how was sputnik 1 famous?
It was the first artificial object to Orbit the Earth
What was sputnik I?
The first man made object put into Earth orbit.
What was the name of the first object in earth?
The first organism on Earth was a bacterium, from what current science tells us. The Earth was composed of single-celled organisms in the beginning of the world.

It was the first artificial (manmade) object to be placed in orbit around the earth. It started the space race between the USA and the USSR.
What information can be found on the Faith First website?
You can find information on the Faith First website about how to teach children religion in a simple form. You can learn more about this program from the Faith First website.
What are you measuring when you put an objecct on a scale?
You're measuring one of the pair of gravitational forces between the Earth and the object. The strength of the forces depends on the mass of the object and the mass of the Earth. It also depends on the distance between their centers, but that's typically just the radius of the Earth (the distance from the Earth's center to the surface). The one we read on the scale is the force attracting the object to the Earth. It's what we call the "weight" of the object on Earth. The other force in the pair acts in exactly the opposite direction. That one is the force attracting the Earth to the object. We don't have to measure it because it has exactly the same strength as the first one. Nobody ever talks about it, but if we did, we would have to call it the Earth's weight on the object.
What was the first spaceship ever made?
The first man made object to orbit the earth was Sputnik 1. Launched by the Russins in 1957
What was the first space satellite of the US?
Explorer 1 was the first US object to be launched into Earth Orbit January 31st, 1958.
What is the significance of Sputnik?
It was the first man-made object to orbit the Earth. It launched on October 4, 1957.
