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

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

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

If the cars final velocity is 50 m/s south and it started with an initial velocity of 60 m/s south. What is happening?

the car has slowed down

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 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? You must use the word "velocity".

decrease in velocity over time

400

For what formula would meters/sec 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 6 seconds at 105.3 m/s?
105.3 m/s
500

100s

500

How would you describe positive acceleration? You must use the word "velocity".

increase in velocity over time

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
