OBJECTIVES

Define acceleration

Differentiate positive, negative acceleration

Solve for acceleration with the formula given

Acceleration 

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

Name the three ways the acceleration changes 

CHALLENGE 

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

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

IMPORTANT 

When an object speeds up it has positive acceleration.

When an object slows down it has negative accelartion 

How fast is the object moving?

The speed in a given direction 

The change in velocity of an object

units 

speed - m/s

velocity- m/s

acceleration - m/s²

What is acceleration?

1. change in velocity
2. change in speed
3. change in position
4. change in direction

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?

1. 16 m/s2
2. 26 m/s2
3. 6 m/s2
4. 60 m/s2

Use the graph below to complete the table below.
Between C and D

1. Object moves forward and slows down.
2. Object moves at a constant velocity
3. object is not moving
4. Object moves forward and speeds up.

Aidan drops a rock from a cliff. After 4.0 s the rock is moving at 39.2 m/s. What is the acceleration of the rock?

Name two words related to acceleration
