## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (4th Edition)

(a) False The mass of an object is measured in kilograms and this mass does not change if the object is in different locations. (b) True The weight of an object is calculated by multiplying the mass and the magnitude of the local gravitational field $g$. The weight can change depending on the magnitude of the local gravitational field. (c) False Mass and weight are not the same thing. The mass tells us how many kilograms of physical material the object is made of while the weight tells us how this mass interacts with the local gravitational field.
