What else can I help you with?
What two factors are necessary to keep the moon and earth in orbit?
Gravity and inertia.
What did the first rocket have to over come to get in to space?
The first rocket had to overcome Earth's gravity to reach space. It needed to generate enough thrust to propel itself upward and break free from the pull of gravity, allowing it to reach the necessary speed to enter into Earth's orbit.
How does the moon crontrol gravity on earth?
No. The earth has its own gravity. The lunar gravity causes tides on earth, but does not control earth's gravity.
How a spaceship gets out of earth's gravity?
A spaceship gets out of Earth's gravity by achieving enough velocity through its engines to overcome the gravitational pull of the Earth. This is typically done during the launch phase using powerful rockets that provide the necessary thrust to propel the spaceship into space. Once it reaches a certain height and speed, the spaceship can then continue its journey in the absence of Earth's gravity.
What is the gravity on Mars compared to earth?
The gravity of Earth is 2.6 times that of Mars.Mars's gravity is 38% of Earth's gravity.
How does the moon's gravity compare to Earth's gravity?
The moon's gravity is about 1/6th of Earth's gravity.
On what day will the earth have no gravity?
Earth will always have gravity for gravity is a result of mass.
What is Charon's gravity compared to Earth's gravity?
The gravity of Charon is about 3% that of Earth.
What is the math for mercury gravity compared to earth?
mercury gravity: earth gravity
Will hurricanes form without gravity?
No, hurricanes require the Earth's rotation and gravity to form. Gravity helps to create the low-pressure systems needed for hurricanes to develop, while the Earth's rotation influences their direction and spin. Without gravity, the necessary conditions for hurricanes to form would not exist.
Is the gravity on earth 1?
Earth's gravity is 1g.
Has earth ever had gravity?
The earth currently has gravity.
