The measure of how much gravitational force is exerted on an object is called weight.

Here's why:

* Weight is the force of gravity acting on an object's mass. It's a measure of how strongly gravity pulls on an object.

* Mass, on the other hand, is the amount of matter in an object. It's a fundamental property of the object itself.

So, while mass stays the same regardless of location, weight can change depending on the gravitational field. For example, you would weigh less on the moon than on Earth because the moon's gravitational field is weaker.
