The force of gravity on the object does in fact stay almost constant, although there is a negligible increase with growing proximity to the earth. An object that is in freefall seemsto be weigh less - in fact nothing - because there is no opposition to gravity. A force is a push or a pull, but we feel forces only when two or more forces push and squash us, or pull us apart. You wouldn't mind an elephant sitting on your head provided their was no ground to be crushed against - likewise with the weighing scale in free fall. There is no ground to push back against it and compress its springs; there is no reaction force, which is what the scale really measures.
What else can I help you with?
Why do you weigh different on objects in space?
Is your question "what do you weigh different objects on in space...", or "why would you attempt to weigh an object in space"...?
When object in elevator and elevator is falling downward then gravity is acting on it but why it is said that in this condition object is weightless?
In a falling elevator, both the elevator and the object inside are accelerating downwards at the same rate under gravity. This creates the sensation of weightlessness, as the object is not experiencing any resistance or contact force from the elevator floor. However, gravity is still acting on the object, causing it to accelerate downwards at the same rate as the elevator.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
When is an object to in free fall?
A falling object.
What is The greatest velocity a falling object?
the greatest velocity a falling object reaches is terminal velocity
What is the greatest velocity a falling object reaches?
the greatest velocity a falling object reaches is terminal velocity
What is the surface area of a falling object?
It depends on the object!
What 2 principal factors affect the force of air resistance on a falling object?
The shape of the object and the density of the gas that the object is falling through.
When equals the force of gravity on a falling object the object reaches terminal velocity.?
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
Do all rocks weigh the same if they have a different mass but the same weight?
Do all rocks weigh the same if they have a different mass but the same weight? Let's look at the question without one bit of it..... "Do all rocks weigh the same if they have ......... .... ... the same weight?" If things are the same weight, then they weigh the same.
How does gravity effect the velocityof a falling object?
In response to the force of gravity, the downward speed of a falling object would increase smoothly, constantly, and continuously, at the rate of 9.8 meters per second faster every second, if it were not for the resistance of the air that a falling object must plow through. This number is called the "acceleration of gravity" on Earth ... it's a different number on the moon and on every different planet.
