There isn't much gravity in empty space, but there is a great deal of gravity near planets, stars, moons and other celestial bodies. The moon has gravity because it has mass. Everything with mass has gravity (including you, albeit a VERY small amount). That's how the astronauts stayed on the moon, and the reason why their movements were slow because the moon has about 1/6 the amount of gravity as Earth.
Neil Armstrong is a famous astronaut who landed on the moon.
No, only Americans have landed on the moon.
Neil Armstrong.
The fourth astronaut on the moon was Mr Alan Bean.
That depends on where He/She is standing: On the moon: Not much different that earth. In a space station: Umm, why is there a boulder in the space station again? Floating in space: He/she would fly backwards and the boulder would move away very slowly. Friction and gravity would keep the person in place on the Earth, moon or space station. However, when they are floating there is no external force. At that point the law of consevation of momentum is in full effect. ( p = m v ) Since the astronaut has a much smaller mass he/she moves more. A similar action-reaction can be seen when firing a standard gun. The bullet has a small mass compared to the person. The bullet moves very fast in one direction while the person only moves a little in the opposite direction.
Yes, it is about 1/3 that on Earth.
The force of gravity between the moon and the planet is what keeps the moon in orbit around the planet. This gravitational force prevents the moon from floating away into space and keeps it in a stable orbit.
Equipment on the moon doesn't float away because the moon's gravity is about 1/6th of Earth's gravity, which is still enough to hold equipment in place. Additionally, there is no air resistance on the moon to push objects around like on Earth.
No. No astronaut has been to the Moon since 1972,
Neil Armstrong was the first astronaut to walk on the moon
The first astronaut to set foot on the moon was the American astronaut Neil Armstrong in the Apollo 11.
An astronaut weighs less on the moon because the moon has less mass than Earth, meaning weaker gravitational force. Weight is the result of the gravitational force acting on an object's mass, so with less force on the moon, the astronaut feels lighter.
Moon buggies do not float away because the moon's gravitational pull keeps them grounded. Unlike on Earth where gravity is stronger, the moon's weaker gravity allows vehicles to roll on the surface without floating away. Additionally, the moon buggy's weight and design are specifically built for use in the lunar environment.
The Earth's gravitational force keeps it from moving away into outer space. (* Gravity is a mutual force of attraction between matter, so the Earth pulls on the Moon while the Moon pulls on the Earth.)
To start off, the moon does have gravity, so you do not have to worry about anything floating away. The lack of pressure is a different matter, as air will escape into the vacuum if given the chance. To keep the oxygen from escaping, astronauts keep it with them in sealed, pressurized vessels.
The astronaut's inertia on the moon would be the same as on Earth, as inertia is an object's resistance to a change in motion. However, due to the moon's lower gravity, the astronaut would weigh less and experience a reduced force opposing their motion compared to Earth.
