Here's why:
* Gravity: Gravity is a force of attraction between any two objects with mass. The Earth has a large mass, so it exerts a strong gravitational pull on objects near its surface.
* Weight: Weight is the force of gravity acting on an object's mass. It's measured in units of force, typically Newtons (N).
Important Note:
* Weight is not the same as mass. Mass is a measure of how much matter an object contains and is constant. Weight, on the other hand, can change depending on the gravitational field the object is in. For example, you would weigh less on the Moon than on Earth because the Moon's gravity is weaker.
