How do objects in space, such as satellites and astronauts, overcome the force of gravity to stay in orbit and avoid falling back to Earth?
Objects in space, like satellites and astronauts, stay in orbit by moving at a high speed horizontally. This speed creates a balance between the force of gravity pulling them towards Earth and their forward motion, allowing them to continuously fall towards Earth without actually hitting it.
What else can I help you with?
What is it when there is no net force of gravity?
When there is no net force of gravity, all the opposing forces of gravity cancel out. For example, most of the way to the moon, the gravity pulling from the moon would cancel out the gravity from the Earth. At that point, there would be no net force of gravity. KEEP IN MIND, that this is something very different from the weightless feeling you get when falling. When falling, gravity still affects you (hence you accelerate downwards). If there is no net force of gravity, gravity will not affect you at all.
Identify the characteristic of gravity that is incorrect?
Gravity is a non-contact force that acts between two masses.
Why are magnets able to overcome force of gravity?
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
A friend says that astronauts in orbit are weightless because they're beyond the pull of earth's gravity correct your friend's ignorance?
Weightlessness in orbit is not due to being beyond Earth's gravity, but rather to being in a state of continuous free fall around the planet. In orbit, the spacecraft and everything inside are falling towards Earth at the same rate, creating the sensation of weightlessness. Gravity is still present in orbit but it is balanced by the spacecraft's forward motion, creating an apparent state of weightlessness.
2 forces that help overcome gravity?
The two forces that help overcome gravity are lift and thrust. Lift is generated by the wings of an aircraft, providing an upward force that counteracts gravity, while thrust is produced by engines to propel the aircraft forward, allowing it to achieve lift and ultimately overcome gravity.
How do astronauts overcome gravity in space?
Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
Why do astronauts float weightlessly in space?
There is (apparent) zero gravity. The absolute gravity in orbit is about 90% of what it is on the surface of the earth, but the effective gravity is zero, and for a good reason.The fact is that in orbit, you are actually falling, but your forward speed is such that the curvature of the planet is dropping at the same rate that you are falling.And the astronauts are falling at the exact same speed as their capsule. This is called freefall.
How do astronauts and satellites stay in orbit when gravity pulls it down?
Astronauts and satellites stay in orbit because they are moving fast enough horizontally that the force of gravity pulling them towards Earth is balanced by their forward momentum. This creates a state of continuous free fall around the planet, resulting in a stable orbit.
Because astronauts are falling through space with their spacecraft they experience this?
Because astronauts are falling through space with their spacecraft, they experience a condition known as microgravity, which creates a sensation of weightlessness. This occurs when both the spacecraft and the astronauts are in free fall towards Earth, creating an environment where the effects of gravity are significantly reduced. As a result, astronauts can float freely within the spacecraft, allowing them to conduct experiments and perform tasks without the constraints of gravity.
Is a satellite weight less Why?
satellites are not weightless. they actually aren't even floating in space. satellites are constantly falling towards the earth but because of their crazy fast speed they constantly miss the edge of the earth and can continue falling. pretty wild stuff gravity is.

Are astronauts in space shuttle in free fall?
It's called micro gravity but basically yes. They are just falling around the planet.
Are astronauts weightless during the Shuttle's launch?
Noop. In fact, as the Shuttle is accelerating, the astronauts are experiencing not only the pull of gravity, but also the acceleration of the rocket. For the comfort of the crew, they try to keep the excess gravity to about 4 G, basically 4 times the pull of gravity. Only after the engines have stopped, and the shuttle is no longer accelerating, will the astronauts feel weightless, as the Shuttle and astronauts are all falling around the Earth at the same speed.
What do you do after sending a space shuttle up?
After a space shuttle is launched it goes in orbit around the Earth. While in orbit, the astronauts preform experiments that can only be done in micro gravity or preform maintenance on satellites, or launch new satellites.
Why do astronauts appear to be floating even though they are still in orbit?
They are essentially in a state of permanent free-fall. Their ship is falling to earth at the same rate as the curve of the earth is falling away form them; ergo continually falling. It has nothing to do anything 'anti-gravity'.
Why dont astronauts hit there heads on the ceiling of the falling shuttle?
Astronauts inside a falling shuttle experience weightlessness because they are in a state of free fall alongside the shuttle. This means both the astronauts and the shuttle are falling together at the same rate, so there is no sensation of hitting the ceiling despite the lack of gravity.
What two examples that illustrate earth's gravitational pull?
1-Apples falling down. 2-Gravity keeps satellites in their orbits around the earth.
