Q2
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.
Q3

Q4
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
Q5
Recently, in a science class test, you are asked a question where you have to say whether the statements are incorrect?
[A]. When the distance travelled is measured in meters and the time taken is measured in seconds then the speed will come in the unit of meters per second.
[B]. When the distance travelled is measured in meters and the time taken is measured in minutes then the speed will come in the unit of meters per minute.
[C]. When the distance is measured in centimeters and the time is measured in seconds then the speed will come in the unit of centimeters per second.
[D]. None of 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

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
