Physics Review Name: ______KEY_______________ 1. Match the following physics terms with their appropriate definition (some can be used more than once): a.Physics b. Scalar c. Vector __b__ quantities that are fully described by a magnitude alone. __b__ speed is an example of this type of quantity __a__ the science of studying the concept of matter and its motion, as well as space and time. __c__ quantities that are fully described by both a magnitude and direction. __c__ velocity is an example of this type of quantity 2. Match the following motion terms with their appropriate definition: a. constant speed b. instantaneous speed c. constant acceleration d. average acceleration e. deceleration __e__ when an object is slowing down. __c__ the SAME change in speed over each equal interval of time. __a__ uniform motion; a consistent change in distance over equal intervals of time. __b__ the speed at which something is traveling at a particular instant in time. __d__ the overall change in speed divided by the change in time. 3. Match the following units with their correct term (some can be used more than once) a. Distance b. Time c. Speed d. Acceleration __c__ km/h __b__ s __d__ m/s2 __d__ km/h/s __c__ mph __b__ min __c__ m/s __b__ day __a__ km __a__ m 4. How many significant figures are in the following measurements? a. 3.450 g _____4________ d. 500 km ______1_______ b. 0.0025 m _____2________ e. 407 s ______3_______ c. 0.3450 cm _____4________ f. 0. m/s ______4_______ 5. Do the following calculations and round the answers to the correct sig. figs. a. 3.543 cm + 35 cm + 0.0578 cm = __38.6008 = 39____ b. 32.5 m x 0.03467 m = __1.__ = __1.13____ c. 500 s – 35.3 s = ___464.7__ = __465____ d. 658 m/s ÷ 32 s = ___20.5625__ = __21__ 6.
