Guided Questions:
1. What is the relationship between
distance and time?
2. How does the distance traveled affect
the time taken?
3. What happens to the time taken as
the distance increases?
4. What does the slope of the distancetime graph represent?
An object’s motion is usually described in
terms of how fast or how slow it is moving.
Is it possible for two objects to
have an equal magnitude of speed
and velocity?
Speed is a measure of how fast
something is moving. It is the rate at
which distance is covered. The word rate
is a clue that something is being divided
by time.
Speed is defined as the distance
covered per unit time.
Speed is also a scalar quantity.
Velocity is a vector quantity. It describes
how fast and in which way (speed +
direction) an object is moving. It can be
negative or positive depending on the
direction of motion
Line graph consists of x and y-axis, each representing a distinct variable. In this
case/lesson, one axis will represent values for distance, and the other for time.
Slope describes the steepness of a graph. It shows the change in the y and x
coordinates of plotted points in the graph. It is usually represented by the
mathematical expression slope of line (m) is equal to rise over run wherein the rise is
the change in the y-coordinates and the run is the change in the x- coordinates.
Distance-Time Graphs
A distance-time graph is a graphical
representation of how far a body has
travelled in a specified amount of time. It is
used to depict the relationship between
distance and time, where distance is
plotted on the Y-axis and time is plotted on
the X-axis. Let’s first learn the importance
of distance-time graphs.
The graphs shown are
distance-time graphs for various
types of body motion.
When a body is steady or
stationary,
When a body is moving at a
uniform speed,
When a body is moving nonuniformly with increasing
speed, and
When a body is moving nonuniformly with decreasing
speed.


If the distance-time graph is a
straight line then the motion is
uniform.
If the distance-time graph of a
body is given, its speed can be
calculated using the slope of
the graph.
The slope of the straight-line
graph is the same irrespective
of the interval which is chosen.
This implies that the speed of
an object under uniform
motion remains constant.
EVALUATION:
Choose and write the letter of the correct answer.
1. What does a distance-time graph represent?
A) The speed of an object over time
B) The distance traveled by an object over time
C) The acceleration of an object over time
D) The velocity of an object over time
2. What does the vertical axis represent on a distance-time
graph?
A. Speed of the object
B. Velocity of the object
C. Distance of the object
D. Total time travelled by the object
3. What does a horizontal line in the distance-time graph
indicate?
A. No movement
B. Constant speed
C. Object is accelerating
D. Object is decelerating
4. What does a line on a graph that is curving upwards mean
in a distance-time graph?
A. The object is not moving.
B. The speed of the object is increasing
C. The object has a constant speed.
D. The speed of the object is decreasing
5. Which of the following options represents the distance-time graph of a stationary
object?
ASSIGNMENT:

1. Calculate the speed of the car during
the fast 10 seconds.
2. How long dis the car stop?
3. What is the speed of the car on its
