Matter and Mass The Difference Between Mass and Weight Weight is the measure of the gravitational force exerted on an object. The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight. Measuring Mass and Weight The SI unit of mass is the kilogram (kg). Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N). Chapter K1

Inertia is the tendency of an object to resist a change in motion. Mass: The Measure of Inertia An object that has a large mass is harder to move and harder to stop than an object that has less mass. The reason is that the object with the large mass has greater inertia. Chapter K1

Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Passage 1 Astronomers were studying the motions of galaxies in space when they noticed something odd. They thought that the large gravitational force, which causes the galaxies to rotate rapidly, was due to a large amount of mass in the galaxies. Then, they discovered that the mass of the galaxies was not great enough to explain this large gravitational force. So, what was causing the additional gravitational force? One theory is that the universe contains matter that we cannot see with our eyes or our telescopes. Astronomers call this invisible matter dark matter. Standardized Test Preparation Chapter K1

Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Passage 2 Blimps and dirigibles are types of airships. An airship consists of an engine, a large balloon that contains gas, and a gondola that carries passengers and crew. Airships float in air because the gases that the airships contain are less dense than air. In the early 1900s, airships were commonly used for travel, including transatlantic flights. Airships were less frequently used after the 1937 explosion and crash of the Hindenburg in New Jersey. The Hindenburg was filled with flammable hydrogen gas instead of helium gas, which is nonflammable. Standardized Test Preparation Chapter K1
