1

The measurement of the change in velocity over time. 

Acceleration 

1

A change in an object's position. 

Motion

1

Quantity of magnitude, but does not include direction. 

Scalar

1

A girl travels 20 miles on her bicycle. The trip takes 2 hours. What is her speed? 

10 mph

1

A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 0.8 m/s and the final velocity was 7 m/s, what was the acceleration of the ball? 

0.413 m/s2

2

Total distance divided by the total time 

Average Speed

2

How fast something is. Distance divided by time. 

Speed 

2

The place that something is located. 

Position 

2

A car starts from a spotlight and is traveling with a velocity of 10 m/s east in 20 seconds. What is the acceleration of the car? 

0.5 m/s2

2

A man walks 7 km in 2 hours and 2 km in 1 hour in the same direction. What is the man's average velocity for the whole journey?

3 km/hr

3

The distance an object is from its starting point. Final position - initial positon. 

Displacement 

3

Some sort of non-moving fixed object with respect to the observer that the observer can use to detect motion. 

Frame of Reference/Reference point

3

The system of measures used in the majority of countries around the world, but not the United States. 

Metric

3

Speed of a rocket that travels 9,000 meters in 12.12 seconds? 

742.57 m/s

3

A man walks 7 km East in 2 hours and then 2.5 km West in 1 hour. What is the man's average velocity for the whole journey?

1.5 km/hr

4
Total length an object travels. 

Distance

4

The system of measures used in the United States 

Customary

4

The ability to see or be aware of something by observation. 

Perception

4

How long will your trip take (in hours) if you travel 350 km at an average speed of 80 km/hour. 

4.38 hours

4

You start walking from a point on a circular field of radius 0.5 km and 1 hour later you are at the same point. What is your average velocity for the whole journey?

If you walk around a circular field and come back to the same point where you started the displacement, which a change in position, is equal to zero. Since the displacement is equal to zero, the average velocity is also equal to zero.

5

A measure that includes both magnitude and direction. 

Vector 

5

Change in displacement over time. The speed of an object in a certain direction. 

Velocity

5

Displacement, Velocity, and Acceleration are considered this type of quantity. 

Vectors

5

How many seconds will it take for a satellite to travel 450 km at a rate of 120 m/s?

3,750 seconds

5

A ball is rolled at a velocity of 12 m/s. After 36 seconds, it comes to a stop. What is the acceleration of the ball? 

-0.33 m/s2
