Define Masses Math

The mass of an object is not dependent on gravity and therefore is different from but proportional to its weight.

Define masses math. M physics a property of matter equal to the measure of the amount of matter contained in or constituting a physical body that partly determines the body s resistance to changes in the speed or direction of its motion. Outside the si system other units of mass include. The atomic mass unit u is 1 12 of the mass of a carbon 12 atom approximately 1 66 10 27 kg. The weight of an object changes according to gravity but its mass remains the same.

This gold bar is quite small but has a mass of 1 kilogram about 2 2 pounds so it contains a lot of matter. In everyday life mass is often called weight but mass and weight are not the same. Mass is the quantity of inertia resistance to acceleration possessed by an object or the proportion between force and acceleration referred to in newton s second law of motion force equals mass times acceleration. Mass is commonly measured by how much something weighs.

Mass can be measured in both metric and customary units. Won numerous awards honors. The slug sl is an imperial unit of mass about 14 6 kg. Mass is often called as weight.

Mass is the quantity of matter in an object. In other words the more mass an object has the more force it takes to get it moving. Kilogram gram and milligram are the metric units whereas ounces and pounds are the customary units. A brick would be weightless in space even though it still has the same mass as on earth.

The atomic mass unit is convenient for expressing the masses of atoms and molecules. A measure of how much matter is in an object. Usually measured in grams kilograms tonnes in the metric system.
