Slide 3 -Slide

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

Slide 4 -Slide

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

Slide 6 -Slide

Name the three ways the acceleration changes

Slide 7 -Slide

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

Slide 9 -Slide

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

Slide 10 -Slide

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

Slide 12 -Slide

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

Slide 14 -Slide

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

Slide 15 -Slide

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

Slide 16 -Quiz

A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down
the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed
is 22 m/s. What is its average acceleration?
A
16 m/s2
B
26 m/s2
C
6 m/s2
D
60 m/s2
