An object’s density tells us how much it weighs for a certain size. The simple explanation is that the heavier object is denser. Two objects may appear identical in size and shape, yet one weighs considerably more than the other. What is volume? Volume is a measure of the amount of three-dimensional space that is being occupied by a liquid, solid, or a gas. *Weight and mass are the two that most often get confused with one another, but we will get back to that. The basic SI unit for weight is a newton. Weight definition in physics Weight is a force that is caused by the gravitational pull of the Earth toward its surface. The kilogram is the basic SI unit of mass. Mass is also the measure of an object’s resistance to gravity. It is approximately the measure of the number of atoms in a given object. DefinitionsWhat is mass? Mass is the measure of the amount of matter. What I’ll do is walk through the definition of each, and then we will go back through and clear up some confusions that lead to these getting misused with one another. Mass, weight, volume, and specific gravity get misused quite often. In this video, I want to focus on what each of these is and how each of them is different. TranscriptHey guys! Welcome to this video on mass, weight, volume, density, and specific gravity. Get the best test prep review for your exam! This video tutorial helps explain the basics of Mass Weight Volume Density and Specific Gravity. Mass, Weight, Volume, Density, and Specific Gravity (Video) Video advice: Using density to find mass or volume You can view the weight as a measure of the mass in kg times the intensity of the gravity field, 9. Another approach is to consider “g” to be the measure of the intensity of the gravity field in Newtons/kg at your location. The value of g allows you to determine the net gravity force if it were in freefall, and that net gravity force is the weight. Weight – You might well ask, as many do, “Why do you multiply the mass times the freefall acceleration of gravity when the mass is sitting at rest on the table?”. Since the weight is a force, its SI unit is the newton. The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.
