Introduction to Physics Conceptual Questions 1.1 The meter (SI unit for length) is defined by the distance light travels in a vacuum in a tiny fraction (1/299792458) of a second. The second (SI unit for time) is defined as the time it takes for 9,192,631,770 periods of the transition between the two split levels of the ground state of the cesium-133 atom. The kelvin (SI unit for temperature) is defined in terms of the conditions under which water can exist as ice, liquid, and gas simultaneously. The kilogram (SI unit for mass) is defined by the mass of a carefully protected prototype block made of platinum and iridium that was manufactured in 1889. 1.2 Yes, it is possible to define a system of units where length is not one of the fundamental properties. For example, a system that has fundamental properties of speed and time can derive the quantity of length. 1.3 Use of the metric prefixe

The kilogram (SI unit for mass) is defined by the mass of a carefully protected prototype block made of platinum and iridium that was manufactured in 1889. 1.2 Yes, it is possible to define a system of units where length is not one of the fundamental properties. For example, a system that has fundamental properties of speed and time can derive the quantity of length. 1.3 Use of the metric prefixes makes any numerical calculation much easier to follow. Instead of an obscure conversion (12 in/ft, 1760 yards/mi, 5280 ft/mi), simple powers of 10 make the transformations (10 mm/cm, 1000 m/km, 1026 m/m). 1.4 The answer should be written as 55.0. When dividing quantities, the number…
