This document is a chapter about motion and speed that includes definitions of key vocabulary words and explanations of concepts. It defines motion as a change in position, and position as the location of an object. Distance is defined as how far an object is from one position to another, and is measured using a ruler or tape measure. Speed is the distance an object moves over a certain amount of time, and is calculated as speed equals distance divided by time. Faster moving objects cover more distance in a shorter time compared to slower moving objects. Maps are used to show the positions of objects and use directions like north, south, east and west to help readers understand locations.

• You can say that something
has moved if it has
changed position.
•
is the location of an object.
When object started at one
end and stopped at another
it changed position.

- Motion can be fast or slow.
Distance
-It is how far an object is from one
position to another.
Measuring the length between
starting position and ending position
give you the distance.
- Measured by: Ruler & Measuring
tape
- Units: Cm, meters & kilometers.

• The cheetah has a greater
speed.
• Is how fast an object
moves over a certain
distance.

speed.
-It is the distance an object moves in
a certain time.
Speed = Distance/Time
So to measure speed you need to
measure time and distance.

13. Ch.9, Lesson 1
Motion and Speed
• Fast moving objects go long
distance in a short period
of time.
• ( 5 meters in 5 minutes)
• Slow moving objects takes
longer to travel the same
distance.
( 5 meters in 10 minutes)

15. Ch.9, Lesson 1
Motion and Speed
• Every map shows directions
below, to help you find
places.
• Map also has a key, to tell
what the symbols stand
for.
• Map also has a
Scale, to help you
Measure the real
Distances between places.
