What is the difference between a truly weightless object and a obect that is weightless because it is free fall?
A truly weightless object experiences no gravitational force, such as an object in deep space far from any massive body. An object that is weightless due to free fall is still under the influence of gravity but is in a state of free fall where the force of gravity and the acceleration of the object cancel out, making it feel weightless.
What else can I help you with?
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.
Why does an astronaut have to exert a force on a weightless object in order to move it?
An astronaut has to exert a force on a weightless object in order to move it because in space, there is no gravity to naturally pull or push objects. Therefore, the astronaut must apply force to overcome inertia and move the object.
What is a situation in which an object is weightless?
An object is weightless when it is in free fall, such as when an astronaut is orbiting the Earth in the International Space Station. In this situation, the object is technically still affected by gravity but experiences a sensation of weightlessness because it is falling at the same rate as its surroundings.
An object in free fall seems to be?
An object in free fall appears weightless because it is falling under the influence of gravity alone, with no other forces acting on it. This gives the illusion that the object is floating or moving effortlessly through the air.
What happens to the rate pf energy transfer between an object and its surroundings if the temperature difference between them is reduced?
If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.

When an object is in free fall is it weightless?
Because the object's inertial motion is equal to the gravitational acceleration. Weight equals mass times gravitational acceleration (W=mg), so you would feel weightless, but your mass stays the same.

How come an object can never be weightless?

If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.

can a weightless body have inertia?
Yes, a weightless body can still have inertia. Inertia is the resistance of an object to changes in its motion, and it is determined by the mass of an object rather than its weight. Even if a body has no weight due to being weightless in space, it will still have inertia based on its mass.
