Of the statements, given below, mark the correct answer as: (a) Both assertion and reason are true and reason is the correct explanation of assertion. (b) Both assertion and reason are true but reason is not the correct explanation of assertion. (c) Assertion is true but reason is false. (d) Both Assertion and Reason are false. Q.1. Assertion : An object may acquire acceleration even if it is moving at a constant speed. Reason : With change in the direction of motion, an object can acquire acceleration.
Answer
Q.2. Assertion : Displacement of an object may be zero even if the distance covered by it is not zero. Reason : Displacement is the shortest distance between the initial and final position.
Answer
Q.3. Assertion : The graph between two physical quantities P and Q is straight line, when P/Q is constant.
Reason : The straight line graph means that P is proportional to Q or P is equal to constant multiplied by Q.
Answer
Q.4. Assertion : Velocity versus time graph of a particle in uniform motion along a straight path is a line parallel to the time axis. Reason : In uniform motion the velocity of a particle increases as the square of the time elapsed.
Answer
Q.5. Assertion : the speedometer of a car measures the instantaneous speed of the car. Reason : Average speed is equal to the total distance covered by an object divided by the total time taken.
Answer
Q.6. Assertion : An object may have acceleration even if it is moving with uniform speed. Reason : An object may be moving with uniform speed but it may be changing its direction of motion.
Answer
Q.7. Assertion : Motion with uniform velocity is always along a straight line path. Reason : In uniform velocity, speed is the magnitude of the velocity and is equal to the instantaneous velocity.
Answer
Q.8. Assertion : If a particle is moving with constant velocity, then average velocity for any time interval is equal to instantaneous velocity. Reason : If average velocity of a particle moving on a straight line is zero for a given time interval, then instantaneous velocity at some instant within this interval may be zero.
Answer
Q.9. Assertion : The displacement of an object can be either positive, negative or zero. Reason : Displacement has both the magnitude and direction.
Answer
Q.10. Assertion : When the displacement of a body is directly proportional to the square of the time. Then the body is moving with uniform acceleration. Reason : The slope of velocity-time graph with time axis gives acceleration.

Answer
Q.3. Assertion : The graph between two physical quantities P and Q is straight line, when P/Q is constant.
Reason : The straight line graph means that P is proportional to Q or P is equal to constant multiplied by Q.
Answer
Q.4. Assertion : Velocity versus time graph of a particle in uniform motion along a straight path is a line parallel to the time axis. Reason : In uniform motion the velocity of a particle increases as the square of the time elapsed.
Answer
Q.5. Assertion : the speedometer of a car measures the instantaneous speed of the car. Reason : Average speed is equal to the total distance covered by an object divided by the total time taken.
Answer
Q.6. Assertion : An object may have acceleration even if it is moving with uniform speed. Reason : An object may be moving with uniform speed but it may be changing its direction of motion.
Answer
Q.7. Assertion : Motion with uniform velocity is always along a straight line path. Reason : In uniform velocity, speed is the magnitude of the velocity and is equal to the instantaneous velocity.
Answer
Q.8. Assertion : If a particle is moving with constant velocity, then average velocity for any time interval is equal to instantaneous velocity. Reason : If average velocity of a particle moving on a straight line is zero for a given time interval, then instantaneous velocity at some instant within this interval may be zero.
Answer
Q.9. Assertion : The displacement of an object can be either positive, negative or zero. Reason : Displacement has both the magnitude and direction.
Answer
Q.10. Assertion : When the displacement of a body is directly proportional to the square of the time. Then the body is moving with uniform acceleration. Reason : The slope of velocity-time graph with time axis gives acceleration.
