Motion and Measurement of Distances Solutions :
(1) Give two examples each, of modes of transport used on land, water and air
Answer :
LAND : The modes of transport used on land are Train and car.
WATER : The modes of transport used on water are boat and ship.
AIR : The mode of transport used air is aeroplane and helicopter.
(2) Fill in the blanks:
(i) One metre is ___ cm.
(ii) Five kilometre is ___ m.
(iii) Motion of a child on a swing is ___
(iv) Motion of the needle of a sewing machine is ___
(v) Motion of wheel of a bicycle is ___
Answer :
(a) 1000
(b) 5000
(c) Periodic
(d) Periodic
(e) Circular
(3) Why can a pace or a footstep not be used as a standard unit of length?
Answer :
The pace or a footstep not be used as a standard unit of length because it is not always equal to every person it varies from person to person hence not use as standard unit of length.
(4) Arrange the following lengths in their increasing magnitude :
1 metre, 1 centimetre, 1 kilometre,1 millimetre.
Answer :
Lengths in increasing magnitude : 1 millimetre, 1 centimetre, 1 meter, 1 kilometre.
(5) The height of a person is 1.65 m. Express it into cm and mm.
Answer :
If the height of a person is 1.65m then the height
→ in cm it is 165 cm.
→ in mm it is 1650 mm.
(6) The distance between Radha’s home and her school is 3250 m. Express this distance into km.
Answer :
We know that 1 km = 1000 m
Then if Radha’s home and her school is 3250 m then it is 3.25 km long
(7) While measuring the length of a knitting needle, the reading of the scale at one end is 3.0 cm and at the other end is 33.1 cm. What is the length of the needle?
Answer :
If we are measuring the length of a needle
The reading of the scale at one end is 3.0 cm and at the other end is 33.1 cm.
Length of needle,
= 33.1 – 3.0
= 30.1
Hence 30.1 is the length of needle
(8) Write the similarities and differences between the motion of a bicycle and a ceiling fan that has been switched on.
Answer :
The similarities and differences between the motion of bicycle and ceiling fan are –
Similarities : Both move in circular motion
Difference : Both have that cycle has two wheels and both circulate and known as rectilinear motion while fan moves at one position only and does not move in rectilinear motion
(9) Why would you not like to use a measuring tape made of an elastic material like rubber to measure distance? What would be some of the problems you would meet in telling someone about a distance you measured with such a tape?
Answer :
Firstly the elastic varies when it is stretched or release and if we measured by a elastic tape then what was its position was it stretched or loosed if it was stretched then the length after measuring is to accurate because the tape is not in same position hence the measurement is wrong and we can’t explain the length to anyone these are the problem while measuring with elastic tape and telling the someone about a distance you measured with such a tape.
(10) Give two examples of periodic motion.
Answer :
In some cases, an object repeats its motion after some time. This type of motion is called periodic motion. Here are some examples
- The movement of a pendulum.
- The movement of a guitar strings.
