Here's a breakdown:
* Weight is the force of gravity acting on an object's mass.
* Mass is the amount of matter an object contains.
* Gravity is a force that pulls objects towards each other. On Earth, gravity pulls objects towards the center of the planet.
Therefore, the heavier an object is (meaning it has more mass), the greater the force of gravity acting on it, and the greater its weight.
It's important to distinguish between weight and mass:
* Mass is a fundamental property of an object and remains constant regardless of location.
* Weight is a force that depends on both mass and the gravitational field. An object's weight can change depending on its location (for example, on the moon, an object would weigh less than on Earth).
