- 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)

• What do Maps tell you?
• is a flat drawing, it shows
position of things.
• To read a map you need to
use directions.
• North, South
• East, West

Map

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.
