Motion & Measurement of Distances

Answers

1.
The metre is the unit of length in SI unit.
2.
Circular Motion
3.
The kilogramme is the unit of weight whereas a kilometre is the unit of length.
4.
It's a rotational motion or rectilinear motion.
5.
Unit
6.
Option A

7.
Motion is defined as a change in position of the object with time is known as motion.
8.
Ship and boat are the examples of the mode of transport used on water. Spacecraft and are aeroplane are the mode of transport used on air.
9.
Unit
10.
Option D

11.
We have seen that arbitrary units are made up of different body parts. These lengths can vary from one person to another. This can create a lot of confusion as there would be no uniformity in measurement.
12.
Option D

13.
Arbitrary measurement is a procedure defined unit is a relative unit of measurement to show the ratio of an amount of substance, intensity, or other quantities, to a predetermined reference measurement.
14.
When we measure some quantity directly, it is called direct measurement. For eg: when you are using a ruler to measure a length, you are doing a measurement.
15.
Periodic motion
16.
Option C

17.
When we measure some quantity indirectly, it is called indirect measurement. For example: when you have to measure the girth of a tree or the length of a curve, you cannot use a ruler. You can use a rope to find the length of a curved line and then compare the length on a ruler.
18.
Option B

19.
