1. Exploring Motion

2. Motion Vocabulary Tells us the rate at which an object moves
Tells us the rate of speed or direction changes.
Is a change in position measured by distance and time
Tells the speed and direction of a moving object.
Motion
Speed
Velocity
Acceleration

3. Distance-Time Graphs Distance Time
Time is always plotted on the X- Axis.
Distance is always plotted on the Y- Axis.

4. Graphing Motion Distance Time
What kind of graph will a non- moving object make?
Have a student stand at the front of the classroom, have another time them for 5 seconds just standing there.
Graph the results.

5. At Rest Objects
How far did the object travel over the time period? Time is increasing to the right, but its distance did not change. The object is not moving. The object is stopped or at rest.

6. Graphing Motion Distance Time
What kind of graph will an object moving at a constant speed look like?
Have a student walk slowly across the room, have another time them for 5 seconds
Graph the results.

7. Constant Speed How far did the object travel over a period of time?
Time is increasing to the right
Distance is increasing constantly with time.
The object moves at constant speed.

8. Graphing Fast Motion Distance Time
What kind of graph will an object moving at a quick but constant speed look like?
Have a student walk quickly across the room, have another time them for 5 seconds
Graph the results.

9. Fast Constant Speed
How far did the object travel over a period of time?
Time is increasing to the right
Distance is increasing constantly with time.
A steeper line means more distance was covered in a given time.
The object moves at constant speed.

10. Graphing Getting faster
Distance
Time
What kind of graph will an object getting faster look like?
Have a student walk slowly for three seconds, and then quickly for two seconds across the room, have another time them for 5 seconds
Graph the results.

11. Getting Faster How far did the object travel over a period of time?
Time is increasing to the right
Why is it not a straight line?
It is not Constant or steady increase
Shows an increase in speed because the line is getting more steep.
The object is accelerating.
