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.
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.
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 force is an upward force that fluids exert on any object that is placed in them?
Buoyant force is an upward force that fluids exert on any object placed in them. It is equal to the weight of the fluid that the object displaces.
What is it when you exert force on an object that causes the object to move?
When you exert force on an object that causes it to move, it is called mechanical work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.

What is the effort force you exert?
The effort force is the force applied by you to move an object. It is the force you exert when pushing or pulling an object. The magnitude of the effort force depends on the weight and size of the object being moved.
How much force does one exert when lifting an object?
The force would be the weight of the object.
When you exert a force on an object it exert the?
When you exert a force on an object, it exerts an equal and opposite force on you, as described by Newton's third law of motion. This means for every action force, there is a reaction force of equal magnitude in the opposite direction.
What force do the sun and the moon exert on the earth?
They exert Gravitational Force on each other. It is a force which is directly proportional to Mass of the object
When you exert a force on an object exerts what force back to you?
According to Newton's Third Law of Motion, when you exert a force on an object, the object exerts an equal and opposite force back on you. This means that for every action, there is an equal and opposite reaction.
Is exert something about force?
Yes. It can be simplified into applying force to an object.
What is ability of a fluid to exert an upward force on an object?
Buoyant force.
