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 = Change in velocity / change in 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?

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 three ways we can tell if something is accelerating?

speeding up, slowing down, changing direction

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

Final Velocity = 50 m/s south.    Initial Velocity = 60 m/s south.    Time to change velocity = 5 seconds.    What is the acceleration of this object?

-2 m/s squared, south

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

A distance vs time graph shows a line with a constant slope. What can you determine about the object's motion?

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

400
How would you describe negative acceleration? You must use the word "velocity".
decrease in velocity over time
400
For what formula would decimeters/hour east be a possible unit?
velocity
400

What does a horizontal line in a distance vs time graph indicate?

The object is at rest (no movement)

500
What is the speed of an object moving east for 6 seconds at 105.3 m/s?
105.3 m/s
500

100s

500

A car brakes hard, decelerating at 50 m/s/s. How long does it take to slow down from 75 m/s to a stop? 

1.5 seconds

500

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

Acceleration

500
What does a horizontal line on an speed vs time graph indicate?
The object is traveling at a same (constant) velocity
