If one assumes that the universe was created from a single batch of energy or a single batch of mass, then an integration over the entire universe of both energy and mass would yield a constant. However integration over apart of the universe for a given time or space interval would yield a changing of both. For instance our sun is always losing energy, as Hydrogen is converted to helium in the Fusion process. This process result in a loss of mass for the sun. But it has plenty to go. Take another section of the universe and you would see a gain in mass as cosmic particles accumulate due to gravitational attraction. I recall presenting this idea of a constant energy/mass to my Physics professor long ago. He felt it was an oversimplification of the universe for which much is unknown. He admired my thinking process though, as so many problems in Physics are solved using conservation theories. Still, look at early models of the atom and how they explained processes without actual sight, as with the Bohr model. Many changes have been added since, but no one really knows. And what about dark matter. A fantastic field Physics is!

Why is it better to use percent change in mass rather than change in mass when analyzing the data?
A percent change in mass is expressed more often than a variable change of mass in order to establish a coordinate for comparison. Your question about why it is better is a bit like asking why do we use specific traffic signs to indicate different driving functions. It is a matter of taste for efficiency purposes. Mass is related to acceleration and it would complicate our preferences to have to think about that all the time.
How will the mass of a rocket change when it has reached outer space?
NO. the rocket will not shrink,grow,compact,or spread out and stay same size.the stuff in it will stay the same,,,,,,,,,,but the weight will change because there is no gravity to pull down on it. (The mass of the rocket will change continuously from the time it leaves the launch pad until sometime after it has reached space. That's because of the fuel mass it loses, as the engines burn. But once the engines cut off, the vehicle's mass doesn't change.)
Will the time period of loaded spring change when taken to moon?
No.Time period of a loaded spring depends on mass and spring constant which are same on Earth aswell as moon.
Is there any object in universe without gravitational force?
Every single thing in the universe that has mass will have gravity (although in some cases it is a really small amount). Although, there has been some theory as to the existence of dark matter (matter which has no mass at all, and is sort of an anti-mass).
When does the moon change shape?
The moon supposedly "changes shape" all the time, as the moon is constantly orbiting the Earth however the moon doesn't actually change shape, it is the amount of the sunlit side of the Earth that we see changing.
Why can't you change the total amount of mass in an object?
Who said you can't do that ? ? You change your own total mass every time you eat breakfast.
What is law conservation of massmatter?
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
Why does the amount of rock change over time?
Erosion caused by wind and water reduces its mass.
Why does mass not change when placed on the moon?
Answer 1: Your mass stays the same all the time because mass is the amount of atoms your made up of. Mass stays the same no matter where you are. The only reason your weight changes is because the gravitational pull on the moon is not a much as it is on Earth. Mass is how much is in you body not on the amount on you weigh
What quantities do not change during a nuclear reaction?
If you consider the equation, E=mc2, you can see that an amount of mass can be considered as equal to an amount of energy. In other words, we could take all the mass in a nuclear reaction and figure out how much energy that represents. If you add that to the amount of energy present at the same time, you get a summation of energy (some of which is mass represented as energy). That amount of energy does not change in a nuclear reaction.
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
Is time dependent on mass energy and distance?
Time is not dependent upon anything. Time is what it is. However, the amount of time necessary for something to happen IS dependent upon the amount of energy put into it, the amount of mass it is happening to and the distance across which it is happening.
Amount of change of one measurment in a given amount of time?
This is the rate, rate of change, or differential with respect to time.
When soda is opened and left out for days does the mass change?
When a can of soda is opened and left to stand, you can expect the following changes over a period of time: -- The CO2 bubbly gas comes out of solution and escapes into the atmosphere, leaving the soda flat. -- Some of the liquid evaporates and escapes into the atmosphere, leaving the level of liquid lower in the can. Since gas and some liquid came out of the can and went elsewhere, there is less mass remaining in the can than there was before it was opened. The total amount of mass doesn't change, but some of it leaves the can and goes to other places. The same change takes place when you drink some of it.
What is. Undulation?
a weather change in an amount of time.

What is the amount of change in a given amount of time?
