MCQ: Distance-Time Graphs - Question 1

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

Detailed Solution for MCQ: Distance-Time Graphs - 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

MCQ: Distance-Time Graphs - Question 2

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

Detailed Solution for MCQ: Distance-Time Graphs - Question 2

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.

MCQ: Distance-Time Graphs - Question 3

### The slope of the distance-time graph is:

Detailed Solution for MCQ: Distance-Time Graphs - Question 3
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.

MCQ: Distance-Time Graphs - Question 4

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

Detailed Solution for MCQ: Distance-Time Graphs - Question 4

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.

MCQ: Distance-Time Graphs - Question 5

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

Detailed Solution for MCQ: Distance-Time Graphs - Question 5
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. .
