Mass is both a property of a physical body and a measure of its resistance to acceleration (rate of change of velocity with respect to time) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Volume A scalar quantity...
Mass and volume are two units used to measure objects.Massis the amount of matter an object contains, whilevolumeis how much space it takes up. Example: A bowling ball and a basketball are about the same volume as each other, but the bowling ball has much more mass. To be precise when...

What is the volume of an object whose density is 2.2 g/cm^3 and has a mass of 50 g? What is the density of an object whose mass is 25 g and whose volume is 10 cm^3? What is the mass of a substance that has a density of 1.25 g/cm^3 and a volume...
The specific volume is an intensive property of a substance. The specific volume of an object is defined as the ratio of the volume of the object to the mass of the object. It is the volume occupied by the unit mass of an object. ...
A sample of metal has a mass of 23.40 g, and a volume of 5.60 mL. What is the density of t
Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
