Why is an object considered weightless when there is no normal force or when an object is in freefall?
An object is considered weightless when there is no normal force acting on it because weight is the force exerted by gravity on an object's mass. In freefall, the object is only subject to the force of gravity, which causes it to accelerate with the same acceleration as the object itself, resulting in a sensation of weightlessness.
Because of freefall astronauts appear this way in orbit?
In orbit, astronauts appear weightless and float because they are in a state of constant freefall towards Earth. Due to the lack of air resistance and the gravitational pull being the only force acting on them, they experience the sensation of weightlessness.
Were else can you find gravity but earth?
Yes. Gravity exists everywhere in the universe as all objects have a gravitational pull. Objects in space do not seem weightless because there is no gravity. Rather they seem weightless because they are in freefall.
What has no gravity?
Technically, nothing is completely without gravity. However, in outer space, astronauts experience a microgravity environment due to the lack of significant gravitational pull from nearby objects. Objects appear weightless in this state because they are in freefall around Earth.
What is the difference between freefall and a non freefall?
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.

Why do astronaut feel weightless in space?
They actually are weightless, due to the fact there is no gravity in space. However a sky-diver would say he/she feels weightless, but they are experiencing free-fall.
How do space shuttles reduce gravity?
They do not. When an object such as the space is in orbit it is essentially in freefall. If you have been n a roller coaster you'll have found that you feel weightless when you are in freefall. The same effect applies on the space shuttle.

What if you experienced freefall?
Experiencing freefall can be thrilling and exhilarating, as you feel weightless and suspended in mid-air. It often occurs when skydiving or base jumping from a high altitude, but proper training and safety equipment are crucial to ensure a safe experience. Adrenaline rush and a sense of freedom are common feelings during a freefall.
When the only force affecting an objects is gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.

In freefall heavier objects fall with a greater acceleration than lighter objects A True b false?
Faulse
What is weightlessness in space?
Weightlessness in space refers to a condition where objects and individuals experience a sensation of being weightless due to the absence of gravitational forces. This occurs when objects are in freefall towards a massive body, like Earth, allowing them to float freely inside a spacecraft. Despite the feeling of weightlessness, the force of gravity is still present, but all objects fall at the same rate due to being in orbit.
What is the difference between freefall and a non freefall?
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
What is the net force that acts on an object that weighs 10 newtons if the objects is freefall?
10 newtons
