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 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, or changing direction

200

What is m/s2 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

Does speed or velocity require a DIRECTION as well as a number?

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 speed or velocity would the units m/s 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
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 squared, east
negative acceleration, decrease in 14 m/s every second
500

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

What is the formula for Acceleration
