* Gravity: A fundamental force that attracts any two objects with mass. The more massive the objects, the stronger the gravitational pull.
* Mass: A measure of the amount of matter in an object.
* Weight: The force of gravity acting on an object's mass.
Key Points:
* Weight is not the same as mass. Mass is a property of an object, while weight is a force.
* Weight depends on both the object's mass and the strength of the gravitational field it's in. For example, an object on the Moon has a lower weight than the same object on Earth because the Moon's gravitational field is weaker.
* The equation for weight is: Weight (W) = Mass (m) x Acceleration due to gravity (g)
In simpler terms: Imagine holding a bowling ball. It has a certain mass. The Earth's gravity pulls on that mass, causing the bowling ball to have weight. The heavier the ball, the more it weighs because the Earth's pull is stronger.
