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