Question

when gravity changes, ____________________ always changes too. which choice below correctly completes the sentence? weight mass matter density

Explanation:

Weight is the force exerted on an object due to gravity (weight = mass×gravity). When gravity changes, weight changes proportionally as mass remains constant. Mass is the amount of matter in an object and is invariant to gravity. Matter is the substance that makes up objects and is not directly related to gravity changes. Density is mass per unit volume and also does not change just because gravity changes.

Answer:

weight
