Why do objects in orbiting space shuttle float?
No Gravity.
What word describes the gravity in orbiting space shuttle?
The word that describes the gravity experienced by an orbiting space shuttle is "microgravity." In this state, objects appear to be weightless because they are in free fall, continuously falling towards Earth while moving forward at high speed. This creates the sensation of reduced gravitational forces, leading to the conditions often referred to as "zero gravity."
What are the forces acting on space shuttle?
The forces acting on a space shuttle during its flight include thrust, drag, gravity, and lift. Thrust is generated by the shuttle's rocket engines, propelling it upward. Gravity acts downward, pulling the shuttle towards Earth, while drag opposes its motion through the atmosphere. Lift, generated by the shuttle's wings, helps counteract gravity during ascent and assists in controlled descent.
What is a orbiting space shuttle?
An orbiter.
What keeps a space shuttle in orbit from falling gack to earth?
A space shuttle remains in orbit due to a balance between its forward motion and the downward pull of Earth's gravity. The shuttle's speed allows it to continually fall toward Earth while also moving tangentially, creating a curved path around the planet. This balance of speed and gravity results in the shuttle orbiting Earth rather than falling back to the surface.
What causes the earth to move on its orbit?
The two motions that cause orbiting are gravity and free fall. Take an orbiting space shuttle for example. The shuttle is in free fall because gravity pulls down on it. The shuttle's path would be straight if not for gravity pulling down on it. The shuttle moves forward at a constant speed and gravity pulls down on it, so the path of the shuttle is curved.
How does the force of gravity on an astronaut orbiting in the space shuttle compare with the force of gravity on the same astronaut when she is standing on the earth s surface?
Gravity is proportional to the mass and inversely proportional to the square of the distance of the centre of the body or bodies.As the shuttle orbits at a comparatively low altitude and the mass remains constant the force diminishes only slightly. Being in free-fall does not mean there is no gravity.
Why does gravity not pull on a space shuddle?
The space shuttle is in a state of free fall around Earth, following an orbit, which counteracts the force of gravity pulling it down. This allows the space shuttle to remain in a stable path without being pulled down by gravity.
What causes the effect of microgravity when the space shuttle is orbiting the earth?
When the space shuttle is orbiting the Earth, the effect of microgravity is caused by the spacecraft and everything inside it being in free fall towards the Earth. The sensation of weightlessness occurs because both the shuttle and any objects inside are falling at the same rate, creating the illusion of zero gravity.
How does weightlessness occur in a space shuttle that is orbiting earth?
Weightlessness is a measure of how much resistance there is between an object and the local gravity. If you are standing on the ground, then there is 100% resistance between you and the pull of gravity. Your weight is equal to the pull of gravity on your mass. When you jump off a tall object, you are falling. You feel weightless because there is no resistance between you and the pull of gravity. When you are in a shuttle orbiting the Earth, both you and the Shuttle are falling in such a way that you never hit the ground. This is called an orbit. You feel weightless because you are falling. You just never hit the bottom like you would on Earth.
Why does a space shuttle need to travel so fast when entering earths atmosphere?
Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.
How does a space shuttle resist gravity when coming back to Earth?
As the space shuttle re-enters Earth's atmosphere, it uses its shape and heat shield to create aerodynamic lift, which counteracts the force of gravity pulling it down. It also utilizes thrusters and control surfaces to maintain a controlled descent trajectory. Additionally, the shuttle's velocity and angle of approach are carefully calculated to reduce the effects of gravity during re-entry.
