## Items in this lesson

Movement
Velocity

#### Slide 1 -Slide

Acceleration and deceleration
- The distance between the pictures increases
but the time remains the same, therefore there is
an acceleration

Acceleration: The velocity increases
Deceleration: The velocity decreases

#### Slide 2 -Slide

Speed at a certain time
Speed at the end
Speed at the beginning
The middle of the different speeds during a certain time

#### Slide 3 -Drag question

Average Speed
What is speed?

The distance coverd in a certain amount of time.

#### Slide 4 -Slide

Variable
Unit 1
Unit 2
Time
seconds (s)
hours (h)
Distance
meters (m)
kilometers (km)
Velocity
meter per second (m/s)
kilometer per hour (km/h)

#### Slide 5 -Slide

Converting km/h to m/s
1 m / s =

#### Slide 6 -Slide

Converting km/h to m/s
1 m / s =
1 m / 1 s =

#### Slide 7 -Slide

Converting km/h to m/s
1 m / s =
1 m / 1 s =
0,001 km / 1 s =

#### Slide 8 -Slide

Converting km/h to m/s
1 m / s =
1 m / 1 s =
0,001 km / 1 s =
0,001 / (1: 3600)h =

#### Slide 9 -Slide

Converting km/h to m/s
1 m / s =
1 m / 1 s =
0,001 km / 1 s =
0,001 / (1: 3600)h =
3,6 km/h

#### Slide 10 -Slide

Converting km/h to m/s
So for m/s to km/h you multiply by 3,6

For km/h to m/s you divide by 3,6

#### Slide 11 -Slide

Calculate Average Speed
vavg=2vstart+vfinal
Make sure you fill in the v in the same way! It is m/s OR km/h!

#### Slide 12 -Slide

Which formula can you use to calculate the average speed of the whole movement shown in the graph?
A
vavg=2(vstart+vfinal)
B
vavg=ts
C
Both
D
None

#### Slide 13 -Quiz

Which formula can you use to calculate the average speed of the whole movement shown in the graph?
A
vavg=2(vstart+vfinal)
B
vavg=ts
C
Both
D
None

#### Slide 14 -Quiz

Which formula can you use to calculate the speed between t2 and t3?
A
vavg=2(vstart+vfinal)
B
vavg=ts
C
Both
D
None

#### Slide 15 -Quiz

Which formula can you use to calculate the speed between 0 and t2?
A
vavg=2(vstart+vfinal)
B
vavg=ts
C
Both
D
None

#### Slide 16 -Quiz

Find:
Vstart en Vfinal for A
Vavg for C
v at 7 seconds
