What is the meaning of ‘acceleration is in the direction of motion’? A. The object is slowing down. B. The object is changing direction. C. The object is at rest. D. The object is speeding up. Explanation: When acceleration is in the same direction as motion, the object’s speed increases.2 / 202. What does the slope of a velocity-time graph represent? A. Distance traveled B. Displacement C. Average speed D. Acceleration Explanation: The slope of a velocity-time graph gives the acceleration of the object.3 / 203. What does a curved line on a distance-time graph represent? A. Object at rest B. Constant acceleration C. Uniform motion D. Non-uniform motion Explanation: A curved line on a distance-time graph indicates non-uniform motion, as the speed is changing. 4 / 204. What does a horizontal line on a distance-time graph represent? A. Uniform motion B. Object at rest C. Accelerated motion D. Non-uniform motion Explanation: A horizontal line on a distance-time graph indicates that the object is at rest, as its position is not changing with time. 5 / 205. What is the path of an object in uniform motion? A. A parabola B. A hyperbola C. A straight line D. A circle Explanation: Uniform motion implies constant velocity, which results in a straight-line path.6 / 206. What does the area under a speed-time graph represent? A. Distance traveled B. Displacement C. Acceleration D. Average speed Explanation: The area under a speed-time graph represents the distance traveled by the object.7 / 207. What does a downward sloping line on a velocity-time graph represent? A. Increasing acceleration B. Object at rest C. Constant velocity D. Decreasing acceleration Explanation: A downward sloping line on a velocity-time graph shows that the velocity is decreasing, implying negative acceleration or deceleration.8 / 208. What does a car’s speedometer measure? A. Average speed B. Instantaneous speed C. Instantaneous acceleration D. Distance traveled Explanation: A speedometer shows the speed of a vehicle at that particular moment.9 / 209. What does a horizontal line on a velocity-time graph represent? A. Object at rest B. Increasing acceleration C. Decreasing acceleration D. Constant velocity Explanation: A horizontal line on a velocity-time graph indicates constant velocity, as the velocity is not changing with time.10 / 2010. What is the term for the motion where an object covers unequal distances in equal intervals of time? A. Accelerated motion B. Decelerated motion C. Non-uniform motion D. Uniform motion Explanation: Non-uniform motion is when an object covers unequal distances in equal intervals of time. 11 / 2011. What is the meaning of ‘acceleration is against the direction of motion’? A. The object is changing direction. B. The object is speeding up. C. The object is slowing down. D. The object is at rest. Explanation: When acceleration is opposite to the direction of motion, the object’s speed decreases.12 / 2012. What is the nature of the distance-time graph for non-uniform motion? A. A horizontal line B. A curved line C. A straight line D. A vertical line Explanation: Non-uniform motion involves changing speed, leading to a curved distance-time graph.13 / 2013. What is the term for the motion where an object covers equal distances in equal intervals of time? A. Non-uniform motion B. Accelerated motion C. Decelerated motion D. Uniform motion Explanation: Uniform motion is when an object covers equal distances in equal intervals of time. 14 / 2014. What is the nature of the velocity-time graph for non-uniformly accelerated motion? A. A vertical line B. A horizontal line C. A curved line D. A straight line Explanation: Non-uniform acceleration leads to a curved velocity-time graph as the velocity changes at a varying rate.15 / 2015. What is the relation between final velocity v), initial velocity u), acceleration (a), and time t)? A. v = u + at^2 B. v = u + 2at C. v = u + 2at^2 D. v = u + at Explanation: This equation relates the final velocity, initial velocity, acceleration, and time for an object moving with uniform acceleration. 16 / 2016. What is the term for the device that shows the distance traveled in automobiles? A. Accelerometer B. Speedometer C. Odometer D. Velocimeter Explanation: An odometer is the device used to measure the distance traveled by a vehicle. 17 / 2017. What does the slope of a distance-time graph represent? A. Displacement B. Velocity C. Speed D. Acceleration Explanation: The slope of a distance-time graph gives the speed of the object. 18 / 2018. What is the meaning of ‘uniform acceleration’? A. The object's velocity changes by unequal amounts in equal intervals of time. B. The object's velocity changes by equal amounts in equal intervals of time. C. The object is at rest. D. The object's velocity remains constant. Explanation: Uniform acceleration means the velocity changes at a constant rate.19 / 2019. What is the meaning of ‘non-uniform acceleration’? A. The object's velocity changes by equal amounts in equal intervals of time. B. The object's velocity changes by unequal amounts in equal intervals of time. C. The object is at rest. D. The object's velocity remains constant. Explanation: Non-uniform acceleration means the velocity changes at a varying rate.20 / 2020. What is the meaning of the signboard showing ‘SPEED LIMIT 50 km/h’? A. Vehicles must travel at a minimum speed of 50 km/h. B. Vehicles can travel at a maximum speed of 50 km/h. C. Vehicles must maintain a constant speed of 50 km/h. D. Vehicles are not allowed to travel at 50 km/h. Explanation: Speed limit signboards indicate the maximum allowed speed on a particular road or area.
