Mass is measured in grams with various prefixes, including milligrams. So 458mg is 458mg of mass.
458mg is 0.458 grams (mg divided by 1,000 = grams)** 1 gram = 1,000mg
mass
The measurement of how much matter is in an object is its mass. Mass is typically measured in units such as grams or kilograms.
Mass is an extrinsic property... that is, it matters very much how much talc there is. Your question makes no sense.
That depends on how much mass there is, how much other mass is nearby, and how far apart the two of them are. If there's no other mass anywhere nearby, then it weighs almost zero.
No, they do not have the same mass. The moon has much less mass than Earth.
A proton has a mass of approximately 1.67 x 10^-27 kilograms.
The suns mass is 332,950 earths.
Yes, a smaller mass can have as much momentum as a larger mass if it is moving at a higher velocity. Momentum is calculated as mass multiplied by velocity, so even if the mass is smaller, a higher velocity can compensate for it.
1 mass = 1200 beads
A proton has a mass of 1 AMU (one atomic mass unit)
No!! Force is how much work is being exerted on an object. NOT how much grav. pull (mass) or how much its accelerating (velocity)!
