Lakhmir Singh & Manjit Kaur Test: Motion - Question 1

### A vector quantity has

Lakhmir Singh & Manjit Kaur Test: Motion - Question 2

### The slope of the x - t graph is a measure of Detailed Solution for Lakhmir Singh & Manjit Kaur Test: Motion - Question 2 Lakhmir Singh & Manjit Kaur Test: Motion - Question 3

### Odometer of automobiles records

Lakhmir Singh & Manjit Kaur Test: Motion - Question 4

Motion of bodies A and B is depicted by the x-t graph. Then which of the following is/are incorrect A: A has uniform motion.
B: B has less velocity than A initially
C: B crosses A at X
D: A comes to rest at X

Detailed Solution for Lakhmir Singh & Manjit Kaur Test: Motion - Question 4

According to the graph given, the body A does not have uniform motion. An object is said to be in uniform motion when it covers equal distances in equal intervals of time. In this case, it accelerates to a particular velocity and remains the same continuously. Otherwise, it is evident that the velocity of B is lesser that A initially and the body B crosses A at X.
Hence, the statement A has uniform motion is not correct.

Lakhmir Singh & Manjit Kaur Test: Motion - Question 5

The speedometer of a car measures

Lakhmir Singh & Manjit Kaur Test: Motion - Question 6

​ From the x - t graph, one can draw the following conclusions ; A: vOA < vAB
B: vBC is negative
C: vCD is the least by magnitude
D: acceleration is uniform

Lakhmir Singh & Manjit Kaur Test: Motion - Question 7

If the displacement-time graph of a particle is parallel to the time axis, the velocity of the particle is

Lakhmir Singh & Manjit Kaur Test: Motion - Question 8

In a uniformly accelerated motion,
A: v - t graph is a straight line not parallel to t or v axis.
B: x - t graph is not a straight line.
C: Slope of v - t graph varies.
D: Slope of x - t graph is constant.

Lakhmir Singh & Manjit Kaur Test: Motion - Question 9

The velocity time graph of a moving particle is shown in Figure, The acceleration of the particle is Lakhmir Singh & Manjit Kaur Test: Motion - Question 10

If the velocity of a body is reducing, it is said to have

Lakhmir Singh & Manjit Kaur Test: Motion - Question 11

The velocity time (v - t) graph of a moving particle is shown in Figure. The acceleration is maximum for segment Lakhmir Singh & Manjit Kaur Test: Motion - Question 12

One can conclude from the given x-t graph that Lakhmir Singh & Manjit Kaur Test: Motion - Question 13

The numerical ratio of displacement to distance for a moving object is

Lakhmir Singh & Manjit Kaur Test: Motion - Question 14

A body starting at a point, say A, reaches, say B, ahead in a straight line and returns back to A. Then there is

Lakhmir Singh & Manjit Kaur Test: Motion - Question 15

From the given v - t graph, it can be inferred that the object is Detailed Solution for Lakhmir Singh & Manjit Kaur Test: Motion - Question 15

In the given graph we find that the velocity is constant throughout, hence the object represented in the v - t graph is said to be in uniform motion.  Zero acceleration is also called uniform acceleration.

Lakhmir Singh & Manjit Kaur Test: Motion - Question 16

A body moves in a circle of radius 5 m with a speed of 5 ms-1. Then it has
A: an acceleration of 5 ms-2
B: an acceleration varying with direction alone

Lakhmir Singh & Manjit Kaur Test: Motion - Question 17

Four cars A, B, C and D are moving on a levelled road. Their distance versus time graphs are shown in figure.
Choose the correct statement. Lakhmir Singh & Manjit Kaur Test: Motion - Question 18

The displacement of the body in 5 seconds from the beginning of the motion is Detailed Solution for Lakhmir Singh & Manjit Kaur Test: Motion - Question 18

Displacement = Area of ΔABC Lakhmir Singh & Manjit Kaur Test: Motion - Question 19

Suppose a boy is enjoying a ride on a merry go round which is moving with a constant speed of 10 ms-1. It implies that the boy is

Detailed Solution for Lakhmir Singh & Manjit Kaur Test: Motion - Question 19

Acceleration is the measure of how fast the velocity changes. Velocity is a vector quantity and a change in velocity is due to  change in magnitude or change in direction or both. Here,  the boy is moving with constant speed but velocity changes and hence is supposed to be in accelerated motion.

Lakhmir Singh & Manjit Kaur Test: Motion - Question 20

The v-t graph shown here depicts the motion of A and B such that ## Science Class 9
