Our weight on the Earth, the Moon, and the Jupiter are different because:
1. difference in the atmosphere
2. difference in the size
3. difference in their gravitation force
4. weight is same in all of them
The correct answer and explanation is:
The correct answer is 3. difference in their gravitation force.
Weight is the force exerted on an object due to gravity. Since gravity varies depending on the mass of the celestial body and its radius, the weight of an object changes on different planets and moons. The gravitational force on Earth, the Moon, and Jupiter is different due to their varying masses and sizes.
On Earth, gravity pulls objects toward the center with a force of approximately 9.8 meters per second squared (m/s²). This constant acceleration creates a gravitational pull that gives us our weight.
On the Moon, gravity is weaker than on Earth because the Moon has only about 1/6th the mass of Earth. Its gravitational acceleration is around 1.6 m/s². This means an object weighs much less on the Moon than it does on Earth.
On Jupiter, the situation is different. Jupiter is much more massive than Earth—about 318 times Earth’s mass. However, it is also much larger in size, which affects its gravitational pull. The gravity on Jupiter is around 24.8 m/s², which is more than twice the gravity on Earth. As a result, an object weighs significantly more on Jupiter than on Earth or the Moon.
Atmosphere and size do influence certain physical properties like air resistance or the ability to sustain life, but the key reason for the difference in weight is the varying gravitational force exerted by each planet or moon. Therefore, an object will weigh differently on the Earth, Moon, and Jupiter primarily due to differences in gravitational force, not because of atmospheric conditions or size alone.
