Science Series 2026 - 06 (Physics) Motion Time Left: 8:00 Question 1: A particle is moving in a circular path of radius "r". The displacement after half a circle would be: Zero 2r Submit Question 2: Which of the following can sometimes be zero for a moving body? Average velocity Distance traveled Average speed None of these Submit Question 3: The slope of a Distance-Time graph represents: Acceleration Speed Displacement Force Submit Question 4: What does a horizontal line (parallel to the time axis) on a Distance-Time graph indicate? Uniform motion Uniform acceleration Object at rest Non-uniform motion Submit Question 5: Which law of motion explains why we jerk forward when a moving bus stops suddenly? Newton`s 1st Law Newton`s 2nd Law Newton`s 3rd Law Law of Gravitation Submit Question 6: The numerical ratio of average velocity to average speed for a moving object is: Always > 1 Always = 1 Always < 1 Submit Question 7: A body thrown vertically upward reaches a maximum height h and then comes back. Its total displacement is: h 2h Zero h/2 Submit Question 8: Inertia of an object tends to cause the object to: Increase its speed Decrease its speed Resist change in motion Decelerate due to friction Submit Question 9: What is the SI unit of Retardation? m/s Submit Question 10: Which of the following is a scalar quantity? Velocity Displacement Distance Acceleration Submit Question 11: When an object travels equal distances in equal intervals of time, it is said to be in: Non-uniform motion Rest Accelerated motion Uniform motion Submit Question 12: The area under a Velocity-Time graph represents: Speed Distance Displacement Acceleration Submit Question 13: What does a straight line sloping upwards on a Velocity-Time graph indicate? Uniform velocity Uniform acceleration Object at rest Variable acceleration Submit Question 14: If the displacement of an object is proportional to the square of time, then the object moves with: Uniform velocity Uniform acceleration Increasing acceleration Decreasing acceleration Submit Question 15: A body moving in a straight line with constant velocity has an acceleration of: Constant value Unity Variable Zero Submit Question 16: In a circular motion at a constant speed, the direction of velocity is: Constant Away from the center Towards the center Tangential to the path Submit Question 17: Why is uniform circular motion called "accelerated motion" even if the speed is constant? Speed changes Direction changes Mass changes Gravity increases Submit Question 18: Which of these is an example of "Inertia of Rest"? Falling forward when a bus stops Passengers leaning sideways in a curve Athlete running before a jump Dust flying off a beaten carpet Submit Previous Next
