Starter- Use the speed to explain the image

#### Slide 3 -Tekstslide

OBJECTIVES
Define acceleration
Differentiate positive, negative acceleration
Solve for acceleration with the formula given

#### Slide 4 -Tekstslide

Acceleration
Acceleartion is a measure of how quickly the velocity of an object changes

#### Slide 6 -Tekstslide

Name the three ways the acceleration changes

#### Slide 7 -Tekstslide

CHALLENGE
Can an object traveling at a constant speed have a changing velocity? Why or why not?

#### Slide 9 -Tekstslide

Where is positive and negative acceleration in this roller coater ride?

#### Slide 10 -Tekstslide

IMPORTANT
When an object speeds up it has positive acceleration.
When an object slows down it has negative accelartion

#### Slide 12 -Tekstslide

How fast is the object moving?
The speed in a given direction
The change in velocity of an object

#### Slide 14 -Tekstslide

units
speed - m/s
velocity- m/s
acceleration - m/s2

What is acceleration?
A
change in velocity
B
change in speed
C
change in position
D
change in direction

#### Slide 16 -Quizvraag

C
6 m/s2
D
60 m/s2
