What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance / Time with a direction
100

What is the formula for acceleration?

Acceleration = 

Vf  - Vi / Time

100
What formula is m/s an example unit?
speed or average speed
100

What can we find with a distance vs time graph?  Think: what can we calculate? 

speed of an object

200
How is speed different from velocity?
velocity needs a direction
200
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
200

What are 3 ways we can tell if something is accelerating?

speeding up,  slowing down, OR changing direction

200
What is km/hr squared, south.. a possible unit for?
Acceleration
200

What always goes on the x axis?

time

300
What is the average speed of a cow that walks east 60 meters in 90 seconds? (Remember, the units must be m/s or km/hr)
.7 m/s
300
Distance = 20 meters Time = 4 minutes Direction = south What is the velocity of this object?
5 m/s south
300

An object is moving south at 60 m/s (Initial Velocity) but slows to 50 m/s (final velocity) in 5 seconds. What is the acceleration of this object?

A = Vf - Vi / Time

-2 m/s/s, south

300
Which of our formulas must have a direction in order to be complete?
velocity
300

On a distance - time graph, what does a straight line in a positive direction indicate about a moving object?

It's moving at a constant speed

400

A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?

40 meters

400

An object travels 25 meters in 2 seconds east. What is it's velocity?

12.5 m/s east (must include direction!)

400

How would you describe negative acceleration? 

decrease in velocity/speed over time

400
For what formula would decimeters/hour east be a possible unit?
velocity
400

What does a horizontal line on a velocity-time graph indicate (if about 0)?

The object is moving at a constant speed 

500
What is the speed of an object moving east for 6 seconds at 105.3 m/s?
105.3 m/s
500
A pink alien moved south in it's spacecraft 2 km at a rate of 20 m/s. How much time did it take him to do this in seconds?
100s
500

How would you describe the acceleration of this object? 

-14 m/s/s, east

negative acceleration, decrease in 14 m/s every second

500
What formula would we use if we wanted to find out how an object's velocity changed within a certain period of time?
What is Acceleration
500

On a velocity-time graph, what does a diagonal straight line at a negative slope indicate?

The object is steadily decelerating (slowing down)
