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

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

It's moving at a constant speed

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

100s

500

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

negative acceleration, decrease in 14 m/s every second
