[A]. The symbols of all units are written in singular.
[B]. Shadow of an object is shortest at noon.
[C]. Roman used sand clocks to measure time.
[D]. A nanosecond is one-millionth of a second.
Q2
Which of the following statement is or are incorrect?
[A]. The movement of an objects is called stationary-motion.
[B]. The movement or duration in which things occurs is called time.
[C]. An object is said to be in motion or moving when its positions changes with time.
[D]. When the position of car changes with, we say that car is moving or that the car is in motion.
Q3
Payel is completed her science chapter where she wrote some statements. She wants to know whether the statements are correct or not? Payel wants to take help from you:
[A]. When an object moves along a straight-line path, it is called rectilinear motion.
[B]. When an object moves along a circular path, it is called circular motion.
[C]. When an object turns or spins about a fixed axis, it is called rotational motion.
[D]. The motion which repeats itself after regular intervals of time, is called oscillatory motion.
Q4

[A]. 0.6 m/s
[B]. 10 m/s
[C]
[C]. 5.4 m/s

Q5
In the last year board examination, Rahul were asked a question where he had to choose the statement which was/were correct? Will you be able to answer this question?
[A]. The unit of speed depends upon the unit of distance and the unit of time used.
[B]. The speed of an object can be calculated by dividing the “distance travelled” by the object, by the “time taken” to travel this distance.
[C]. The “distance traveled” divided by “time taken” actually gives us “average speed” of the car during that time.
[D]. All the above
Q6
In a science quiz competition, Payel are asked a question where she had to choose the statement which was/were correct?
[A]. If we have to compare the speeds of a number of objects, then we must express the speed of all those objects in the same units.
[B]. An instrument on a vehicle dashboard which indicates the speed of the vehicle when it is running is called speedometer.
[C]. An odometer it is an instrument for measuring the distance travelled by a vehicle.
[D]. All the above
Q7
Consider the following statements and choose the incorrect one:
[A]. The distance time graph of an object moving with a uniform speed or constant speed is a straight line.
[B]. The Slope of a distance-time graph indicates the speed of the object.
[C]. The distance time graph for an object moving with non-uniform speed is a curved line.
[D]. When the distance travelled is measured in kilometers and the time taken is measured in hours then the speed will come in the unit of meter per hour.
Q8
Bikash is doing his homework which is given by his teacher. Would you help him to choose the correct sentences?
[A]. If the distance time graph of an object is a straight line then it is moving with a constant speed
[B]. If the distance time graph of an object is not a straight line or curved line than the speed of an object is not constant.
[C]. The distance time graph of an object is a horizontal line parallel to the time axis, then the speed of object is zero and the object is not moving.
[D]. All the above
