MCQ Science and Technology Class 9 Chapter 1 Maharashtra Board Laws of Motion 1. What defines motion according to the document?Change in temperature of an objectChange in position of an object relative to its surroundingsChange in mass of an objectChange in shape of an objectQuestion 1 of 202. Which example from the document indicates an object in motion?A stone lying on a hillA stationary trainLeaves flying through airA book on a tableQuestion 2 of 203. How does the document differentiate distance from displacement?Distance is a vector; displacement is a scalarDistance is the actual path travelled; displacement is the minimum distanceBoth are identical in all casesDistance is the minimum path; displacement is the actual pathQuestion 3 of 204. What is the displacement of an object after completing one round in a circular path?Equal to the circumferenceZeroEqual to the radiusTwice the radiusQuestion 4 of 205. What is the formula for speed as per the document?Speed = Displacement / TimeSpeed = Acceleration × TimeSpeed = Total distance travelled / Time requiredSpeed = Velocity / TimeQuestion 5 of 206. How is velocity defined in the document?Mass multiplied by accelerationDisplacement in unit timeTotal distance in unit timeChange in speed over timeQuestion 6 of 207. What is the SI unit of speed and velocity mentioned in the document?km/hcm/sm/s²m/sQuestion 7 of 208. When do speed and velocity have the same value for an object?In circular motionWhen the object is at restIn straight-line motionDuring decelerationQuestion 8 of 209. If a motorcycle’s speed increases but its direction remains constant, what happens to its velocity?Velocity becomes zeroVelocity decreasesVelocity increasesVelocity remains constantQuestion 9 of 2010. If a motorcycle’s direction changes but speed remains constant, what happens to its velocity?Velocity remains unchangedVelocity changesVelocity becomes zeroVelocity doublesQuestion 10 of 2011. Who first measured speed as distance divided by time, according to the document?EinsteinNewtonGalileoKeplerQuestion 11 of 2012. What is the approximate speed of light given in the document?343.2 m/s3 × 10⁸ m/s29770 m/s60 km/hQuestion 12 of 2013. What characterizes uniform speed in the document?Covering unequal distances in equal time intervalsChanging direction constantlyMoving with constant accelerationCovering equal distances in equal time intervalsQuestion 13 of 2014. What is non-uniform speed according to the document?Covering equal distances in equal time intervalsCovering unequal distances in equal time intervalsMoving with zero accelerationMoving in a circular pathQuestion 14 of 2015. What is acceleration defined as in the document?Rate of change of distanceRate of change of velocityRate of change of speedRate of change of displacementQuestion 15 of 2016. What is the formula for acceleration provided in the document?a = v × ta = (v - u) / ta = (v + u) / ta = u / tQuestion 16 of 2017. What is the initial velocity of an object at rest, as per the document?1 m/sZero9.8 m/sUnknownQuestion 17 of 2018. What term is used for negative acceleration in the document?Uniform accelerationZero accelerationDecelerationPositive accelerationQuestion 18 of 2019. When does an object have zero acceleration?When velocity increasesWhen velocity decreasesWhen velocity is constantWhen direction changesQuestion 19 of 2020.
