Science Series 2026 - 03 (Physics) Motion Time Left: 8:00 Question 1: When a body is dropped from a height, its initial velocity (u) is taken as: 9.8 m/s 1 m/s Infinite Zero Submit Question 2: A ball is thrown up and reaches the top. What is the direction of its acceleration at the top? Upwards Zero Downwards Horizontal Submit Question 3: Which of the following is an example of non-uniform motion? Light in vacuum Train starting from station Earth`s rotation Pendulum in vacuum Submit Question 4: The rate of change of displacement is known as: Speed Acceleration Velocity Momentum Submit Question 5: The slope of a velocity-time graph gives: Distance Displacement Speed Acceleration Submit Question 6: If a body moves with a constant speed in a straight line, its velocity is: Constant Increasing Decreasing Zero Submit Question 7: Non-uniform acceleration means: Velocity changes equally Body is at rest Velocity is constant Velocity changes unequally Submit Question 8: Which law describes the relationship between force and acceleration? Newton`s 1st Law Newton`s 2nd Law Newton`s 3rd Law Law of Inertia Submit Question 9: Which graph shows uniform motion? Straight line in distance-time graph Curved line in distance-time graph Straight line in velocity-time graph Horizontal line in acceleration-time graph Submit Question 10: Displacement can be: Equal to distance Less than distance Both A & B All of these Submit Question 11: A body moving in a circular path has: Uniform speed Uniform velocity Zero acceleration Constant displacement Submit Question 12: If velocity decreases, acceleration is: Positive Negative Zero Infinite Submit Question 13: Average speed is defined as: Total distance/total time Total displacement/total time Change in velocity/time Final velocity/initial velocity Submit Question 14: Average velocity is defined as: Total distance/total time Total displacement/total time Change in velocity/time Final velocity/initial velocity Submit Question 15: A body at rest has: Zero speed Zero velocity Zero acceleration All of these Submit Question 16: Non-uniform motion means: Constant speed Constant velocity Variable speed or velocity Zero acceleration Submit Question 17: Which of the following is not a unit of speed? m/s km/h cm/s m/s² Submit Question 18: If a car covers 60 km in 2 hours, its average speed is: 30 km/h 60 km/h 120 km/h 15 km/h Submit Question 19: If a body moves 10 m east and then 10 m west, displacement is: 20 m 0 m 10 m 5 m Submit Question 20: Which of the following is correct?
