This document contains questions and answers related to the topic of motion. It includes short answer questions about translatory motion and its types, whether a person sitting in a moving bus is at rest or in motion, converting a distance in meters to kilometers, defining uniform and non-uniform motion, and precautions for using a meter scale. Long answer questions ask for examples of different types of motion, how rectilinear motion differs from circular motion, differentiating between distance and displacement, and whether displacement can be zero if distance is positive or if displacement can exceed distance traveled.

Q: What is translatory motion? What
are its types?

Q: What is translatory motion? What
are its types?
Ans: The motion in which a body
moves as a whole and every point on
it moves the same distance is called
translatory motion.
Translatory motion is of three types:
(i) Linear motion
(ii) Curvilinear motion
(iii) Random motion.

Q: If you are sitting in a moving bus,
are you at rest or in motion?

13. 13
Q: If you are sitting in a moving bus,
are you at rest or in motion?
Ans: If we are sitting in a moving bus, we
are not changing our position in
comparison to things inside the bus.
According to the definition of motion, we
are not moving. The bus is moving. In other
words, we can say that we are in motion in
comparison to outside trees and other
buildings and stationary in comparison to
things inside the bus.

Q:Ramesh’s mom asked him to go get
paneer from the market. The market
is 1550 m from his home. Express this
distance into km

Q:Ramesh’s mom asked him to go get
paneer from the market. The market
is 1550 m from his home. Express this
distance into km
Ans: We know that 1 km = 1000 m
Or, 1000 m = 1 km
Or, 1m = 1/1000 Km
Thus, 1550 m = (1/1000) X 1550 = 1.55 Km
Therefore, distance between Ramesh’s
home and the market in km = 1.55 km

Q: Define Uniform and Non-uniform
Motion.

17. 17
Q: Define Uniform and Non-uniform
Motion.
Ans: Uniform motion: It is a motion, in which
equal distance is covered in equal time
intervals.
Non - uniform motion: It is a motion, in
which unequal distance is covered in equal
intervals of time.

Q: State two precautions, which should
be taken while using a metre scale to
measure the length of an object.

19. 19
Q: State two precautions, which should
be taken while using a metre scale to
measure the length of an object.
Ans: Two precautions are:
Place the scale in contact with the object
along its length.
Most important, eye should be correctly
positioned above the point to be measured
to make a correct measurement

Q: Give examples of periodic and
oscillatory motions.

21. 21
Q: Give examples of periodic and
oscillatory motions.
Ans: Examples of periodic motion are:
motion of moon around the earth
heart-beat in a healthy person
motion of earth around the sun
Examples of oscillatory motion are:
motion of pendulum of wall clock
a child on a swing
motion of heart muscles in a healthy
person.

Subjective Questions
LONG ANSWER TYPE

23. 23
Q: A. Give two examples for each of
the following. a. Circular motion
b. Random motion
c. Vibrational motion
B. How is rectilinear motion different
from circular motion?

24. 24
Ans: A.
Rotation of fan, motion of earth around
the sun.
Flow of water in river, motion of dust
particles.
String of a guitar when struck, beating
the surface of drum.
B. When objects move along a straight
line such motion is called rectilinear
motion. Whereas when an object moves in
a circular path, such motion is called
circular motion

25. 25
Q: a. Differentiate between distance
and displacement.
b. Can the displacement of an object
be zero but positive distance?
c. can the displacement of an object
be more than the distance travelled
by it.

26. 26
Ans: a. Distance is a quantity that refers
to "how much ground an object has
covered" during its motion from one point
to the other. Or, the total length travelled
from one point to another.
Displacement is the shortest distance
travelled from one point to another.
b. Yes, it is possible to have a positive
distance yet zero displacement. When the
object returns back to its origin after
travelling, then the displacement is zero.
c. No, it is not possible. Displacement can
never be more than distance,by definition
displacement is the shortest distance
between the point of origin and position
of the object after travelling.
