MCQ Tests with Answers for Class 7 Science Chapter 13
Q1
Consider the following statements and choose the incorrect one:
[A]. The symbols of all units are written in singular.

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
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.

[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

[A]. 1.6 s
[B]. 2.6 s
[C]. 3.6 s
[D]. 4.8 s
Q7
Which of the following statement is or are incorrect?
[A]. An object moving along a straight-line path is said to have uniform motion if its speed remains constant.
[B]. An object moves moving along a straight-line path is said to have non uniform motion if its speed keeps changing.
[C]. The non-uniform motion (in which the speed of an object keeps changing) is also called accelerated motion.
[D]. None of the above
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
Q9
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
Q10
Consider the following statements and choose the correct one:
[A]. Time is a moment or duration in which things occur.
[B]. In ancient times, people used some natural events which repeated regularly after fixed time, intervals to measure time.
