First a Reviewof

• Speed, Velocity, Acceleration

SPEED
SD/T
The distance an object travels in one unit of
time.
4
VELOCITY
The speed in a particular direction.
5
Change in Speed divided by the amount of time it
takes to occur.
ACCELERATION
Positive Acceleration

MOTION GRAPH CHALLENGE

1. Be sure you know your physics stuff about
   speed, average speed, velocity, acceleration, and
   deceleration.
2. Interpret the following motion graphs to the best
   of your knowledge.
3. You may work with one other person to help you
   solve the challenges.

INTERPRET THE GRAPH BELOW

1. What is the graph showing? Speed, Velocity,
   Acceleration, Deceleration?
2. How do you know?
3. Explain what is happening in the graph.
4. Is the motion constant? How do you know?

8
Answers to the GRAPH BELOW
What is the graph showing? Speed, Velocity,
Acceleration, Deceleration? Speed How do you
know? Distance vs. Time
9
Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
The object is not moving because the distance is
not increasing or decreasing as time passes.
10
Answers to the GRAPH BELOW
Is the motion constant? Yes How do you know? It
is a straight line

13
Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
As time increase distance is increasing steadily,
there is no acceleration or deceleration.

17
Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
As time increases, distance is increasing
drastically there is a definite acceleration.
18
Answers to the GRAPH BELOW
Is the motion constant? No How do you know? The
line is curved up showing acceleration (an
increase in speed)

21
Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
As time increases distance is increasing
steadily, then the object is at rest, then the
object changes direction and is moving backwards
at a slower speed.
22
Answers to the GRAPH BELOW
Is the motion constant? No How do you know? The
line is not straight, it shows a stop and
different movements in different directions

Answers to the GRAPH BELOW
What is the graph showing? Speed, Velocity,
Acceleration, Deceleration? Change in velocity
over time (acceleration) How do you
know? Velocity is on the y-axis
25
Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
The graph showsthat the objects velocity does
not change as time passes.

Answers to the GRAPH BELOW
Explain what is happening to the object shown in
this graph.
The graph showsthat the objects speed is
decreasing as time passes it is decelerating.
34
Answers to the GRAPH BELOW
Is the motion constant? No How do you know? Speed
or Velocity is decreasing
