Which of these has the most mass? a. a laser beam b. a rocket in space c. a pitched baseball d. a stationary baseball

the answer is ( . a rocket in space )

The correct option is B

Explanation:

The mass of an object is the amount of substances/molecules present in that object. The mass of an object remains the same anywhere regardless of gravity. In space, where there is no gravity, the mass of a rocket remains the same but the weight will be different because of zero gravity which means there will be no force of gravity pulling the rocket towards itself.

Hence, weight can be calculated as

Mass of an object (in kg) × gravitional field strength (in N/kg)

From the above formula, it can be deduced that weight is dependent on mass and gravity but mass is not (when you make mass the subject of the formula).
