MCQ Tests with Answers for Class 7 Science Chapter 13
Q1
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.
Q2
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
Q3
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 โdistance travelledโ by the object, by the โtime takenโ to travel this distance.
[C]. The โdistance traveledโ divided by โtime takenโ actually gives us โaverage speedโ of the car during that time.
[D]. All the above
Q4
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
Q5
If we denote speed by S, distance by D and time by T, the relationship between these quantities is:
[A]. S = D x T
[B]. T = S/D
[C]. S = 1 x D/ T
[D]. S = T/D
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
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
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.
[C]. A sundial measures time by the position of the shadow cast by the sun.
[D]. All the above
