## physics quiz units and measures

The units that can be expressed independently are called fundamental or base units. For example- mass is expressed in kilogram, length in metre, and time in second respectively are fundamental units. The units for which a combination of the fundamental units is called derived units. The base units for length, mass and time in unit systems are:. CGS System: centimetre, gram and second. FPS System: foot, pound and second.

When you have completed the practice exam, a green submit button will Physics Quiz : Measurement Units. You measure the mass of a block five times and get the following values: 0. The true mass is known to be 0. How would you characterize your measurements? One mole of aluminum atoms has a mass of 27 grams.

The thumbnail image is of the Whirlpool Galaxy, which we examine in the first section of this chapter. Galaxies are as immense as atoms are small, yet the same laws of physics describe both, along with all the rest of nature—an indication of the underlying unity in the universe. In this text, you learn about the laws of physics. Galaxies and atoms may seem far removed from your daily life, but as you begin to explore this broad-ranging subject, you may soon come to realize that physics plays a much larger role in your life than you first thought, no matter your life goals or career choice. It operates on a vast range of scales involving length, mass, and time.
