#### Slide 2 -Link

OBJECTIVES
relate the description of an object's position on a reference point
compare and contrast speed and velocity
describe acceleration

#### Slide 3 -Tekstslide

lesson 1- Position and motion
A reference point is a starting point you choose to describe the location, or position of an object.
A position is an object's distance and direction from a reference point
Motion is the process of changing position
distance depends on the path taken and displacement depends on final and initial positions

#### Slide 4 -Tekstslide

The man is in motion compared to which reference point?
A
the boat
B
the buoy
C
the fishing line
D
the ocean

#### Slide 5 -Quizvraag

Which of the following requires knowing only distance, direction, and a reference point?
A
speed
B
position
C
velocity
D
acceleration

#### Slide 6 -Quizvraag

Displacement measures the _________ between the starting and stopping points.
A
distance and direction
B
distance and speed
C
direction and speed
D
mass and volume

#### Slide 8 -Tekstslide

Lesson 2- Speed and velocity
Speed is a measure of distance an object travels per unit time
Velocity is the speed and direction of a moving object
velocity changes when speed and direction of an object changes.

#### Slide 9 -Tekstslide

Which is distance divided by time?
A
acceleration
B
speed
C
velocity
D
position

#### Slide 10 -Quizvraag

Describe three ways the ball can change velocity

#### Slide 11 -Open vraag

lesson-3 Acceleration
Acceleration is a measure of the change in velocity during a period of time

#### Slide 13 -Tekstslide

When something slows, its acceleration is __________.

B
instantaneous
C
negative
D
constant

#### Slide 14 -Quizvraag

When something accelerates then stops accelerating, what happens to the object?
A
it slows
B
it goes faster
C
it stops completely
D
it continues to move at a constant velocity

#### Slide 15 -Quizvraag

An object that has the same speed but changes direction is __________.
A
slowing down
B
speeding
C
accelerating
D
displacing

#### Slide 16 -Quizvraag

unit of velocity
unit of acceleration
speed

#### Slide 17 -Sleepvraag

What is the speed of this car?
A
6 m/s
B
9 m/s
C
12 m/s
D
18 m/s

#### Slide 18 -Quizvraag

A
10 m/s
B
1.7 m/s
C
1.7 m/s^2
D
10 m/s^2
