Weight Comparison: Object on Moon vs. Earth
The weight of an object is the force exerted on it by gravity. This force depends on the mass of the celestial body and the object's mass.
Weight can be represented by the formula W = mg, where W is weight, m is mass, and g is the acceleration due to gravity.
Key Factors
- Mass of Celestial Body: The Moon has considerably less mass than the Earth.
- Gravitational Acceleration (g): Gravity is directly related to mass. Less mass means weaker gravitational pull. Therefore, the acceleration due to gravity on the Moon (gMoon) is less than on Earth (gEarth).
- Weight Dependency: Since weight (W) is calculated as mg, a smaller value for g results in a smaller weight, assuming the object's mass (m) remains constant.
Because the Moon's mass is smaller, its gravitational acceleration is weaker. Consequently, an object's weight on the Moon will be less than its weight on Earth.
The correct option states that the weight is Less on the Moon.
