False. Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of how much matter there is in an object. In everyday usage, mass is more commonly referred to as weight, but in physics and engineering, weight means the strength of the gravitational pull on the object; that is, how heavy it is, measured in units of force. In everyday situations, the weight of an object is proportional to its mass, which usually makes it unproblematic to use the same word for both concepts. Thus 100 grams would normally weigh 3.52739 oz (not 100 oz)
To make a 100 gram mass weigh 100 oz you would need to increase the strength of gravity more than 28 times.
False. The weight of an object can vary depending on the gravitational force acting upon it.
True. The buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid that the object displaces. Therefore, by knowing the weight of the object, you can determine the buoyant force on it.
It is not the same. Read the Wikipedia article on "mass versus weight" for a detailed discussion.
False. The weight of an object can change depending on its location in the universe due to variations in gravitational force. Weight is a measure of the force of gravity acting on an object, and this force can differ in different locations.
That is true! Weight is how much gravity is pulling on an object. For example, on the moon, an object will weigh about 6 times less than it does on Earth. Mass, on the other hand, stays the same ALL THE TIME, no matter where you are.
False. The weight of an object can vary depending on the gravitational force acting upon it.
False It should read: The amount of matter in an object is its mass (not weight)
True. The buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid that the object displaces. Therefore, by knowing the weight of the object, you can determine the buoyant force on it.

2nd answer: In fact, weight = mass if the massive object is on Earth.
False. The weight of an object can change depending on its location in the universe due to variations in gravitational force. Weight is a measure of the force of gravity acting on an object, and this force can differ in different locations.
That is true! Weight is how much gravity is pulling on an object. For example, on the moon, an object will weigh about 6 times less than it does on Earth. Mass, on the other hand, stays the same ALL THE TIME, no matter where you are.
True. According to Archimedes' principle, an object placed in a fluid will experience a buoyant force equal to the weight of the fluid it displaces. If this buoyant force is equal to the weight of the object, the object will float.
TRUE
False. Weight is a measure of the force of gravity acting on an object, while a kilometer is a unit of distance. The weight of an object depends on its mass and the strength of the gravitational field it is in.
True. Mass and weight are related through the effect gravity has on an object. Mass represents the amount of matter in an object, while weight is the force of gravity acting on that object. Weight is directly proportional to mass and the acceleration due to gravity.
