What is a physical quantity?A type of materialA quantity like mass or speed that can be measuredA unit of timeA direction onlyQuestion 1 of 202. What is used to express the magnitude of a physical quantity?A value and a unitA direction onlyA color codeA symbol aloneQuestion 2 of 203. Which of the following is a scalar quantity?VelocityDisplacementMassWeightQuestion 3 of 204. What is required to completely express a vector quantity?Magnitude onlyDirection onlyMagnitude and directionA unit aloneQuestion 4 of 205. What is mass a measure of?Gravitational forceInertia of an objectDistance traveledSpeed of movementQuestion 5 of 206. Why does an object with larger mass have greater inertia?It moves fasterIt resists change in its state moreIt has less weightIt changes direction easilyQuestion 6 of 207. What is the gravitational force acting on an object called?MassWeightVolumeDensityQuestion 7 of 208. Why is weight considered a vector quantity?It has only magnitudeIt has magnitude and directionIt does not changeIt is measured in gramsQuestion 8 of 209. Where is the weight of an object maximum?At the equatorAt the polesAt sea levelAt high altitudeQuestion 9 of 2010. Why is the weight of an object less at high altitude?Gravity increasesGravity decreasesMass increasesMass decreasesQuestion 10 of 2011. What unit is used to measure mass?MetreKilogramSecondLitreQuestion 11 of 2012. What does a two-pan common balance compare?WeightsMassesVolumesDistancesQuestion 12 of 2013. Why can’t one unit measure all physical quantities?They are all the sameEach quantity is differentUnits are unavailableMeasurements are inaccurateQuestion 13 of 2014.
