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 = Final Velocity - Initial Velocity / change in time with a direction
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 120 meters in 20 seconds east?

6 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)

0.7 m/s or 0.66666 (rounded up it is 0.7 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

What does a distance vs time graph with a straight (linear) line indicate about a moving object?

It's moving at a constant speed

400

A porcupine moved toward a pond at a speed of 6 m/s. It took him 9 seconds. What was the distance he traveled?

54 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? 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 velocity graph indicate?

The object is at rest (no movement)

500

What is the speed of an object moving east for 5 seconds at 126.3 m/s?

126.3 m/s

500

A pink alien moved south in it's spacecraft 5 km at a rate of 20 m/s. How much time did it take him to do this in seconds?

250 s

500

How would you describe the acceleration of this object? - 14 m/s squared, 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

What does a horizontal line on an speed vs time graph indicate?

The object is traveling at a same (constant) velocity
