Here's why:
* Weight is the force of gravity acting on an object's mass. It's directly proportional to the object's mass and the gravitational acceleration of the planet or celestial body it's on.
* Mass is the amount of matter in an object. It's a fundamental property of an object and remains constant regardless of location.
Key difference:
* Weight changes depending on the gravitational field strength.
* Mass remains constant.
For example:
* An object with a mass of 10 kg on Earth would have a weight of approximately 98 Newtons (N), since Earth's gravitational acceleration is roughly 9.8 m/s².
* The same object on the Moon would have a weight of approximately 16 N, because the Moon's gravitational acceleration is about 1.6 m/s².
So, while the object's mass stays the same, its weight changes depending on the gravitational pull it experiences.
