Recall a fundamental postulate of relativity -- that one can not define the velocity of an object except in reference to a frame. Thus, we can NOT say an object is "speeding" unless we also define against which frame we are making measurements.
In an object's own frame, its own mass never changes.
In a frame that views such an object as "speeding," the mass of the object will be greater than it is in its own frame.
Not "mistaken to be" greater, not "viewed as" greater, not "seems to be" greater, not "appears to be" greater. The mass IS greater in that second frame.
If the mass of an object increases, what happens to the acceleration?
An object's mass remains the same regardless of its distance from the center of the Earth. Mass is an intrinsic property of an object that does not change with its location in space.
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
If the mass of an object remains constant, and the amount of space underwater it takes up (it displacement) increases, the buoyant force on the object will increase. The object will rise until it regains equilibrium, when it displaces the same mass of water as its own mass.
If you measure the mass of a movjng object as it moves through your laboratory, you'll always find that it has more mass than it had when it was just sitting on the shelf. The faster it's moving through your laboratory, the greater its mass will be. It doesn't matter whether it's accelerating or not.
Yes, mass takes up space because mass is a measure of matter in an object, and matter occupies physical space. The more mass an object has, the more space it takes up.
If the volume is tripled while the mass remains constant, the density of the object will decrease because density is mass divided by volume. This means that the object will become less dense and occupy more space.
Objects have mass and occupy space. Persons have mass and occupy space.
Mass is the amount of material in an object. Mass has weight, volume, takes up space, and is measurable.
The properties that describe how much space an object takes up are volume, density, and mass. Volume measures the amount of space an object occupies, density is the mass per unit volume of an object, and mass is the amount of matter in an object.
No, the mass of an object does not change based on its location. Mass is an intrinsic property of an object that remains constant regardless of its position in space.
Increasing volume without increasing mass usually means the object becomes less dense. This can happen by adding air or expanding the space the object occupies. The mass remains the same, but the density decreases.
