Question

Why sometimes does the mass of an object change if you measure it using two different balances?

Answer 1

Answer:

Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height. ... The less massive the object is, the more the force of air resistance slows the object down as it falls.

Answer 2

Mass simply indicates the amount of actual stuff present, not the size of an object or the force exerted on it. A measure of how much stuff (or matter) is in an object. This is not to be confused with the terms "weight" or "volume."

Explanation:

• let's just start with weight and bulk. The mass of an object is the quantity of matter it contains.
• Mass and weight are not the same thing: an object's mass will remain constant regardless of where it is in the Universe, but its weight will not.
• If I had a certain amount of anything, say an apple, and transported it from Earth to the Moon, I would still have one apple (provided I didn't get hungry).
• Unless I eat it, I will always have the same quantity of apple no matter where I store it. This indicates that my apple has the same mass whether it's on Earth or on the Moon. The kilograms is the unit of mass.
• Now, weight is defined as the mass multiplied by the gravitational force, or how strongly a planet pulls an object towards itself.
• Returning to our apple, wouldn't it be a lot easier to raise and put in my mouth on the Moon than it would be on Earth? Because the Earth's pull (gravity) is stronger than the Moon's, the Earth pulls on the apple harder than the Moon.
• My apple weighs more on Earth than it does on the Moon, despite the fact that I have the same amount of goods and the same mass.
• Weight is defined as mass multiplied by acceleration, where acceleration refers to the gravitational force that pulls objects toward the ground.
• The unit of weight is Newtons, which is equal to the mass (kilograms) multiplied by the acceleration (meters per second). But, when we ask for the weight of something, how can we get units of mass? This is due to the fact that the scales we use to measure weight take into account the acceleration of the Earth's pull on the object.
• This component is constant on Earth, which means that if you are on Earth, it will always be the same. If I'm on the moon and my apple weighs.$25$ Newtons, I'll need to know the moon's acceleration of gravity to calculate its mass.
• Because everything on Earth accelerates at the same rate, things of varying masses will still hit the ground at the same time if dropped from the same height.
• No one will believe you the first time you say that because everyone has dropped a marble and a feather at the same moment and they have all landed at different times.
• This isn't due to changes in acceleration, which are constant on Earth; rather, air is pushing against the object in the opposite direction as the Earth pulls. Air resistance is the source of this power.
