* Mass: The amount of matter in an object. It's a fundamental property and remains constant regardless of location.
* Weight: The force of gravity acting on an object's mass. It's not the same as mass!
* Force: A push or pull that can cause a change in an object's motion. Gravity is one type of force.
Here's the key:
* Weight is the force due to gravity acting on an object's mass.
Think of it this way:
* You have a bowling ball (mass).
* On Earth, gravity pulls on that bowling ball, resulting in its weight.
* If you took the bowling ball to the moon, its mass wouldn't change, but its weight would be less because the moon's gravity is weaker.
In short: Weight is the force of gravity on an object's mass.
