What measures the quantity of matter
The mass of an object is a fundamental measure of the amount of matter in it. The symbol for mass is m & its SI unit is the kg.

- Q: true / false: Volume is an unreliable measure of the quantity of matter.true / false: Accuracy and precision have the same meaning.An object weighs 39.36 newtons. What is its mass if a gravitometer indicates that g = 9.83 m/sec2?the first two problems dont have spcific answers in my books and i have looked everywhere.also can you tell me on the last one how to find the answer ive looked in my books but am having a hard time understanding it.
- A: Accuracy and precision are not the same thing. The number pie is approximately 3.14159. If I say that pie is 3 this number is accurate but not precise. It is accurate because I am simply stating that pie is closest to 3. I am saying nothing about it beyond that. It is imprecise because there is much fuzziness in my response. Pie could be as large as 3.4999 and as small as 2.500001. If I say that pie is 3.14 this number is accurate and more precise than 3. There is more precision because I have told you more about pie and there is less doubt about what number I'm talking about. If I told you pie was 3.0000000. This would be a very precise answer but not an accurate answer. It is precise because there is much information here but it its inaccurate because most of the information is wrong.For the second one. W = mg. The weight is 39.36 newtons. G is 9.83 m/sec2. Just solve the equation.
- Physics Question: Mass?
- Q: Which of the scientists (Antoine Lavoisier, Issac Newton, and Albert Einstein) might have said the following?a. The mass of a body is a measure of the quantity of matter in the body.b. The mass of a body is the body's resistance to a change in motion.c. The mass of a body depends on the body's velocity.To what extent are these statements compatible or contradictory?I think I'm pretty sure that (a) is Lavoisier (Law of Conservation of Mass) and (b) is Newton (Law of Inertia) but that means (c) is Einstein and I have no idea why or maybe I just got the first two wrong?
- A: You got it right.a and c have to be incompatible, the quantity of matter doesn't change with velocity, so either a or c is wrong.b doesn't conflict with either.So which is right, a or c. Einstein showed that to a stationary observer, a moving body has more mass than a stationary body. It is why physicists build huge accelerators and smash particles into each other. At speeds significantly less than the speed of light, the increase in mass is small but as the particle nears the speed of light instead of going a lot faster it gets a little faster and a lot heavier. That is why a particle with a non zero rest mass (eg protons neutrons electrons) can't travel at the speed of light, they just get heavier the harder you try.
