Question

1. how is weight different from mass? mass can change where weight cannot. weight and mass are interchangeable. mass accounts for the force of gravity on an object. weight accounts for the force of gravity on an object.

Explanation:

Mass is the amount of matter in an object and is constant. Weight is the force exerted on an object due to gravity ($W = mg$, where $W$ is weight, $m$ is mass, and $g$ is the acceleration due to gravity). Since $g$ can vary (e.g., different planets have different gravitational accelerations), weight can change.

• Mass cannot change easily (unless matter is added/removed), so the first option is wrong.
• Weight and mass are not interchangeable (different physical quantities, different units), so the second option is wrong.
• Mass does not account for the force of gravity. Weight ($W=mg$) does, using the mass and the gravitational acceleration.

Answer:

Weight accounts for the force of gravity on an object.
