100
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 is the unit for speed?

Meters per second (m/s)

100

What goes on the X-Axis of a motion graph?

Time

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

What is the speed of a cow that walks 60 meters in 90 seconds? REMEMBER TO INCLUDE YOUR UNIT!!

0.7 m/s

300

A person walks 20 meters south in 4 seconds.What is the velocity of this person?

5 m/s south

300

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

-2 m/s squared

300

If a car is starting at rest, what is its initial speed? Include the correct unit!

0 m/s

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 traveled 105 meters to go grab some food. It took him 18 seconds. What was the speed he was traveling at?

5.83 m/s

400
An object travels 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400

If you get a negative answer when calculating acceleration, what does that mean?

The object is slowing down.

400

What is the unit for acceleration?

Meters per second squared (m/s2)

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 student is going on a trip to Colorado over Spring Break. They drove 321,000 meters to reach Colorado in 14,400 seconds. What was their velocity?

22.29 m/s WEST

500

There is a car that starts from rest and speeds up to a final speed of 200 m/s. It takes the car 10 seconds to speed up.

A student says that this car has an acceleration of 20 m/s. What is wrong with this students statement?

The student used the wrong unit. It is m/s2

500

What units are used for distance and time in science class?

You must get them both right to get the points!

Time= Seconds

Distance = Meters

500

What does a line going down on a motion graph indicate?

The object is going back to where it started.
