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.
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 is the mass of an object on earth that will weigh the same amount as if you were on the moon?
The Greeks about 400 BCE first determined the distance to the moon, sort of. They did this by noting the ratio of the time it took earth's shadow to cross the lunar surface to the length of time of the lunar orbit. The ratio was about 60 to 1, indicating the moon was 60 earth diameters away. The earth's diameter is about 8000 miles, so the lunar distance is roughly 240,000 miles. What the Greeks did NOT know was what the earth's diameter was, so they really didn't know, at least for about 200 years, how far away the moon REALLY was. Finally, about 250 BCE, Eratosthenes determined the diameter of the earth, and the last bit of information fell into place.
What was the purpose of the Mercury program?
The purpose of the Mercury program was to send man into space for the first time, orbit around the Earth, find out how a person functioned in space, and to recover the astronaut and spacecraft safely.
What was first object to reach the moon?
The first object to reach the moon was the Soviet spacecraft Luna 2, which impacted the moon on September 13, 1959. Luna 2 was part of the Luna program and its primary goal was to impact the moon and send data back to Earth.

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.
What was the First Man made object to circle the earth in 1957?
The first man-made object to circle the Earth in 1957 was the Soviet satellite Sputnik 1. It was launched on October 4, 1957, and marked the beginning of the space age.
Why is sputnik 1 famous?

What was the name of the early space program?
The early space program was named the "Mercury Program," which was NASA's first human spaceflight program. The program aimed to launch astronauts into Earth's orbit and was active from 1958 to 1963.
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.
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 came first the Apollo program or the Gemini program?
The Gemini program came first. It was a precursor to the Apollo program and its main goal was to develop the techniques needed for the Apollo missions to the moon. The Apollo program followed the Gemini program and its main objective was to land humans on the moon and bring them back safely to Earth.
