The Earth’s atmosphere is mixture of gases held around the planet by its gravitational force. The constant movement of molecules within the ... WebOn Earth, g is about 10 N/kg. This means that a 2 kg object on the Earth’s surface has a weight of 20 N (2 kg × 10 N/kg = 20 N). Mass and weight

WebThe force of gravity, or gravitational force, pulls objects with mass toward each other. We often think about the force of gravity from Earth. This force is what keeps your body on the ground. But any object with mass exerts a gravitational force on all other objects with mass. For example, there is a gravitational force between you and every ... WebCorrect option is D) We observe weightlessness in satellite because the net magnitude of force on the body is almost zero i.e. earth's gravitation is nullified in terms of magnitude by centrifugal force. But, earth's gravitation is necessary to change the direction of satellite continously and thus providing the acceleration in terms of change ... flag for the earth
