Questions:

Generic 3

5 x 3 = 15

One day, a five years old boy, Chintoo was playing with his toys in his room. After few minutes, he saw a wristwatch on his study table, so after seeing it, he got crazy and so much in eager to play with that watch. Then, for 2 to 3 min, he was trying to analyse it that whether its a toy or something else, then suddenly, he was just about to throw it but at the same his mother entered into the room and take the watch back immediately from his hand.
(a) State the benefit of a wriswatch.
(b) Briefly mention the values showed by Chintoo's mother here.

Briefly mention how many types of motion are there. Also, name all of them.

Differentiate between a uniform and non-uniform motion.

Show the shape of the distance-time graph for the motion in the following cases:
(a) A car moving with a constant speed.
(b) A car parked on a side road.

The odometer of a car reads 57321 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also.

Distance between Bholu's and Golu's house is 9 km. Bholu has to attend Golu's birthday party at 7 0' clock. He started his journey from his home at 6 0' clock on his bicycle and covered a distance of 6 km in 40 min. At that point, he met Chintu and he spoke to him for 5 min and reached Golu's birthday party at 7 0' clock. With what speed, did he cover the second part of the journey? Calculate his average speed for the entire journey.

(a) The wristwatch can be handled very easily to check the time in comparison to the wall clock.
(b) The values showed by Chintoo's mother here is the concern towards her four years old child and also the concern towards that wristwatch while considering the importance of money.

Different types of motion are there and they can be named as follows
(i) Periodic motion
(ii) Rolling motion
(iii) Rotatory motion
(iv) Oscillatory and vibratory motions
(v) Translatory motion

When a body travels equal distance in an equal interval of time, then the body is said to be in a uniform motion.
When a body travels unequal distance in an equal interval of time, then the body is said to be in non-uniform motion.

As, we know that
\(Speed=\frac{Distance\ covered}{Time\ taken}\)
Given, distance covered = 57336 - 57321=15km
Time taken = 8: 50 AM- 8: 30 AM= 20min
\(Speed=\frac{15}{20}=\frac{3}{4}km/min\)
Now, speed in km/h is given by \(\frac{3}{4}\times60\)
= 45 km/h \([1min=\frac{1}{60}h]\)

Multiple Choice Question

(d)
4(t₁+ t₂)

(d)
By multiplying with 5/18

(a)
Distance = Speed \(\times\) Time

(d)
m/s

(b)
\(Speed=\frac{Distance}{Time}\)

11.

When the object is at rest, then the distance-time graph of an object is a horizontal line parallel to the axis of time.

12.

Before the discovery of pendulum clocks, sundials, water clocks and sand clocks were used.

13.

If an object covers more distance in equal intervals of time with respect to other, then we can say that object is moving faster with respect to the other object.

14.

y-axis represents the dependent variable.

15.

The most common thing in almost all the clocks is that all of them shows periodic motion.

Generic 5

2 x 5 = 10

16.

From the question, Bholu covers 3 km distance in 15 min
speed of Bholu \(=\frac{3}{15}\times60=12\ km/h\) \((1\ min=\frac{1}{60}h)\)
Now, average speed is given by
\(=\frac{Total\ distance\ travelled}{Total\ time\ taken}=\frac{9}{1}=9\ km/h\)

17.

(a) From the graph, it is clear that the distance at 20 s is 8 m.
(b) Distance travelled by the body object in 12 s is 6 m.
(c) \(Average\ speed=\frac{Total\ distance}{Total\ time}=\frac{8}{20}=0.4m/s\)
