ncert class 6 science motion and measurement of distances question 3

Why can a pace or a footstep not be used as a standard unit of length?

cbse class 6 science motion and measurement of distances Answer 3

A pace or a footstep cannot be used a standard unit of length as length of footstep or hand span of different person is different. Thus, the measurement will not be the same for different people.

ncert class 6 science motion and measurement of distances question 4

Arrange the following lengths in their increasing magnitude:
1 meter, 1 centimeter, 1 kilometer, 1 millimeter.

cbse class 6 science motion and measurement of distances Answer 4

1 kilometer (km) = 1000 meter (m)
1 meter (m) = 100 centimeter (cm)
1 centimeter (cm) = 10 millimeter (mm)
Hence, the ascending order of given unit is as follows:
1 millimeter < 1 centimeter < 1 meter < 1 kilometer.

ncert class 6 science motion and measurement of distances question 5

The height of a person is 1.65 m. Express it into cm and mm.

cbse class 6 science motion and measurement of distances Answer 5

The height of a person is 1.65 m.
As we know 1 meter = 100 cm; and 1000 mm
Thus, 1.65 m = 1.65 × 100 = 165 cm;
= 1.65 × 1000 = 1650 mm.

ncert class 6 science motion and measurement of distances question 6

The distance between Radha’s home and her school is 3250 m. Express this distance into km.

cbse class 6 science motion and measurement of distances Answer 6

The distance between Radha’s home and her school is 3250 m.
I kilometer = 1000 m
So, 3250 m = 3250/ 1000 Km
= 3.25 Km

ncert class 6 science motion and measurement of distances question 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 33.1ccm. What is the length of the needle?

cbse class 6 science motion and measurement of distances Answer 7

The reading of the scale at one end is 3.0 cm.
The reading of the scale at the other end is 33.1 cm. Thus, the length of the needle is = 33.1 cm – 3.0 cm = 30.1 cm

ncert class 6 science motion and measurement of distances question 8

Write the similarities and differences between the motion of a bicycle and a ceiling fan that has been switched on.

cbse class 6 science motion and measurement of distances Answer 8

Similarity: Both the wheel of a bicycle and ceiling of fan execute a circular motion on a fixed axis. Dissimilarity: A bicycle executes a rectilinear motion while a ceiling fan does not execute rectilinear motion.

Why could you not use an elastic measuring tape to measure distance? What would be some of the problems you would meet in telling someone about a distance you measured with an elastic tape?

cbse class 6 science motion and measurement of distances Answer 9

Elastic tape gives incorrect measurement because the length of elastic tape varies and depends upon the force by which it is stretched. It would be difficult to tell someone about the extend by which tape was stretched while measuring the distance with elastic tape.

ncert class 6 science motion and measurement of distances question 10

Give two examples of periodic motion.

cbse class 6 science motion and measurement of distances Answer 10

Motion of a pendulum and motion of a Child on the swing are examples of periodic motion where an object or a part of it repeats its motion after a fixed interval of time.
