Question

An empty box has a mass of 5 kilograms. You put a few objects into the box. Now the mass of the box increases to 25 kilograms. Which of the following statements is true?

A. When the mass increases, the amount of force needed to lift the box decreases.
B. When the mass increases, the amount of force needed to lift the box increases.
C. When the mass increases, the amount of force needed to lift the box remains the same.
D. When the mass increases, the amount of force needed to lift the box is not affected.

Answer 1

When the mass of the box increases, the amount of force needed to lift the box increases.

Step-by-step explanation:

In this scenario, when the mass of the box increases from 5 kilograms to 25 kilograms, the amount of force needed to lift the box increases. This is because the force required to lift an object is directly proportional to its mass. As the mass of the box increases, more force is needed to counteract the gravitational force pulling it downwards. Therefore, option B, 'When the mass increases, the amount of force needed to lift the box increases,' is the correct statement.
