I've heard terms like solid mass,or maybe still mass and I'm sure there are others so can I get a little education?

Natsirt said:OK I'm glad to hear its not as complicated as I thought it would be. So why are those Mass terms used in the first place?

jtbell said:Can you give us quotations that show how these terms were used, in context? In particular, I've never heard of "still mass."
I wonder if these might be bad translations into English. If that is the case, seeing how they are used would help us tell you what the proper English terms are.
Natsirt said:I'm sorry my knowledge on the subject is very little. I actually meant to say rest mass.
Natsirt said:What is the difference between measuring a mass when your at rest relative to said mass and not being at rest relative to said mass?
When not at rest, you measure the mass to be higher. The greater the relative speed, the greater the mass.Natsirt said:What is the difference between measuring a mass when your at rest relative to said mass and not being at rest relative to said mass?
Natsirt said:So when subatomic particles are going near the speed of light the amount of energy creates a measurable amount of more mass?

Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass is a constant property of an object, whereas weight can vary depending on the strength of gravity.
Rest mass refers to the mass of an object when it is at rest, while relativistic mass takes into account the effects of motion and energy on an object's mass. Relativistic mass increases as an object's velocity approaches the speed of light.
In physics, there are three types of mass: inertial mass, gravitational mass, and rest mass. Inertial mass is a measure of an object's resistance to changes in its motion, gravitational mass is a measure of an object's response to gravitational forces, and rest mass is the mass of an object at rest.
Mass is typically measured using a balance or scale. The standard unit of mass in the International System of Units (SI) is the kilogram (kg). Mass can also be measured indirectly through its effects on other objects, such as in the case of gravitational mass.
According to the law of conservation of mass, mass cannot be created or destroyed, only transformed from one form to another. In other words, the total mass of a closed system remains constant over time.
