1. SPEED In this section you will review how to calculate the speed of an
object
interpret distance time graphs
be introduced to the idea of average speed

2. . __ Speed = Copy these notes and equation into your books:-
To work out the speed something is travelling with
we need to measure 2 things:-
the the object has travelled
the it takes for the journey
Speed = __ .
(in metres) (in seconds)
(in metres per second or m/s)

3. . __ Speed = distance time
Copy these notes and equation into your books:-
To work out the speed something is travelling with
we need to measure 2 things:-
the distance the object has travelled
the time it takes for the journey
answers
Speed = distance time __ .
(in metres) (in seconds)
(in metres per second or m/s)

4. speed
= m
Speed = m/s
= s

5. answer
Constant
speed
12-4=8m
Speed = 8/3
Speed = 2.67m/s
6-3=3s

6. Constant speed of Average speed of 1.2m/s
Fill in the missing speeds
Average speed of 2.4m/s (changes direction)
Average speed of 1.2m/s

7. Constant speed of 1.5m/s
0m/s
1m/s
6m/s
0m/s
4m/s
4m/s
2m/s
Average speed of 2.4m/s (changes direction)
Average speed of 1.2m/s
