MCQ: Distance-Time Graphs - Question 1

In a distance-time graph, if the line is horizontal, then the object is:

Detailed Solution: Question 1

When an object is at rest it will not be able to cover any distance . So for any object at rest the distance -time graph is horizontal to time axis

Topic in NCERT: Distance-Time Graphs

Line in NCERT: "Distance-time graphs can be employed under various conditions where objects move with uniform speed, non-uniform speed, remain at rest etc."

MCQ: Distance-Time Graphs - Question 2

The area under speed-time graph represents a physical quantity which has the unit of?

Detailed Solution: Question 2

Area under a s-t graph represents a physical quantity which is Distance.
Area under the s-t graph will always give distance.
And distance has a unit of m.

MCQ: Distance-Time Graphs - Question 3

The acceleration of an object moving in a straight line can be determined from:

Detailed Solution: Question 3

The slope of velocity- time graph represents the acceleration. Since straight line is inclined to the time axis, slope is uniform  and constant, acceleration will be uniform.

Topic in NCERT: VELOCITY-TIME GRAPHS

Line in NCERT: "The area under the velocity-time graph gives the distance (magnitude of displacement) moved by the car in a given interval of time."

MCQ: Distance-Time Graphs - Question 4

If the speed-time graph is a straight line parallel to the time axis, then the body is

Detailed Solution: Question 4

It is in uniform motion because it is travelling equal distances in equal intervals of time

Topic in NCERT: VELOCITY-TIME GRAPHS

Line in NCERT: "The height of its velocity-time graph will not change with time."

MCQ: Distance-Time Graphs - Question 5

On the distance-time graph, the Y-axis should be labeled as:

Detailed Solution: Question 5

Independent variables are plotted along X-axis and Dependent variables are plotted along Y-axis. In the distance-time graph, time is independent and distance is a dependent variables. Y-axis is Distance

Topic in NCERT: DISTANCE-TIME GRAPHS

Line in NCERT: "In this graph, time is taken along the x-axis and distance is taken along the y-axis."

MCQ: Distance-Time Graphs - Question 6

The slope of the distance-time graph is:

Detailed Solution: Question 6

The gradient of a distance-time graph represents the speed of an object. The velocity of an object is its speed in a particular direction. The slope on a velocity-time graph represents the acceleration of an object. The distance travelled is equal to the area under a velocity-time graph.

Topic in NCERT: DISTANCE-TIME GRAPHS

Line in NCERT: "We can use the distance-time graph to determine the speed of an object."

MCQ: Distance-Time Graphs - Question 7

For a body performing motion with uniform speed, the distance-time graph is:

Detailed Solution: Question 7

For a body moving at uniform speed, the distance time graph is a straight line inclined to the time axis, which may pass through origin or some other point on the y- axis.

As in uniform motion, the distance time graph would be a straight line, because the equal distance is covered in equal units of time. 

Topic in NCERT: Distance-Time Graphs for Non-Uniform Motion

Line in NCERT: "The distance-time graph for the motion of the car is shown in Fig. 7.4. Note that the shape of this graph is different from the earlier distance-time graph (Fig. 7.3) for uniform motion."

MCQ: Distance-Time Graphs - Question 8

What is the slope of distance-time graph when object is at rest?

Detailed Solution: Question 8

Since The Body is at Rest ,It clearly means that The Body hasn't covered any Distance here.So,Distance is equal to zero.So,There is no meaning of having any slope here.. So,The Slope=0 Becoz The Distance at anytime will represent same point in Distance-Time Graph at 0..So,(B)is d correct answer. .

Topic in NCERT: DISTANCE-TIME GRAPHS

Line in NCERT: "Distance-time graphs can be employed under various conditions where objects move with uniform speed, non-uniform speed, remain at rest etc."

MCQ: Distance-Time Graphs - Question 9

In a distance-time graph, which variable is plotted on the Y-axis?

Detailed Solution: Question 9

Answer: d) Distance

Explanation: In a distance-time graph, distance is plotted on the y-axis and time on the x-axis.

MCQ: Distance-Time Graphs - Question 10

The following graph shows the distance–time relationship for two objects, A and B, starting from the same point.

  • The slope of a distance–time graph represents the speed of the object (the greater the slope, the higher the speed).
  • Observe the two straight lines: line A has a smaller slope, while line B has a steeper slope.

2698_image006

Based on the graph, which statement is true about the speeds of object A and object B?

a) The speed of object B is greater than the speed of object A
b) The speed of object B is less than the speed of object A
c) Both objects have the same speed
d) None of the above

Detailed Solution: Question 10

The graph shows two lines for objects A and B on a distance-time graph.

Key observations:

  • The slope of the distance-time graph indicates the speed of the object.
  • The line for B is steeper than the line for A, meaning that object B has a higher speed than object A.

Correct option: Option A: Speed of object B is greater than object A.
