The document discusses position vs. time and velocity vs. time graphs for objects with constant velocity motion. It explains that a position vs. time graph of constant velocity motion shows a straight line with a constant slope, representing constant velocity. A velocity vs. time graph of constant velocity motion is a horizontal line, showing that the velocity does not change over time. The document provides examples of these types of graphs.

1. The Position vs. Time
and Velocity vs. Time
Graphs of Constant
Velocity Motion

2. OBJECTIVE:
At the end of the lesson, you should
be able to explain how the position
vs. time and velocity vs. time
graphs of constant velocity motion
are different from those of constant
acceleration motion

3. Recall the following terms of the basic
quantities that describe motion.
DISTANCE
DISPLACEMENT
SPEED
VELOCITY
ACCELERATION
DECELERATION

4. Distance is the total length or ground covered
by an object.
Displacement is the change in the position of
an object or the shortest distance between
the initial and the final position of an object .
Speed is how fast the object is moving and can
be calculated by dividing the total distance by
the total time spent to cover that distance.

5. Velocity is how fast and where the object is
moving and can be calculated by dividing the
displacement of an object to the time spent.
Acceleration is the change in the velocity of an
object per unit time. An object accelerates
when there is a change in the object’s speed,
direction, or both speed and direction
Deceleration is the negative acceleration.

6. An object is said to be in motion when
its position changes relative to a
reference point, usually the ground.
The motion of an object can be
described in different ways; it can
be described using distance,
displacement, speed, velocity, and
acceleration.

7. Motion can also be presented
graphically like the position
vs. time and velocity vs. time
graphs which show the type of
motion an object undergoes in
a unit of time.

8. POSITION VS. TIME GRAPH OF
CONSTANT VELOCITY
A position vs. time graph of
a body moving with
constant velocity in a
straight path will look like
the

10. The graph shows that as time goes by,
the body changes position by the same
amount; hence, it shows a straight line
with a slope slanting to the right. The
slope of a position vs time graph
represents velocity. If we calculate the
slope of this line, we will get a constant
value that corresponds to the velocity of
the body.

11. VELOCITY VS. TIME GRAPH OF
CONSTANT VELOCITY
The velocity vs. time time
graph of a body moving
with constant velocity
looks like the graph
below.

13. The graph shows that as time goes
by, the body's velocity does not
change; hence, the graph is a
horizontal line. If we calculate the
slope for this line which
corresponds to the body’s
acceleration, it will reveal this
value:
