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
Read the following sentences carefully, and choose the incorrect one:
[A]. The distance moved by an object in a unit time is called speed of the object.
[B]. A slow-moving object is said to have a low speed.
[C]. A fast-moving object is said to have high speed.
[D]. None of the above
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

Q8
In the last year board examination, Rahul were asked a question where he had to choose the statement which was/were incorrect? Will you be able to answer this question?
[A]. The variation of distance travelled by an object with time can be seen more easily from a distance time graph than table form.
[B]. A bar graph is a diagram which shows information as bars of different heights.
[C]. A pie chart is a kind of graph or diagram which shows the percentage composition of something in the form of slices of a circle.
[D]. None of the above
