Instructions:

Answer 14 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. Constant speed or velocity
Start a problem by asking 'What is the object doing?' - 'What is causing it to do that?' - What direction is it moving in (if two find x and y components)? Is it moving at constant v (this includes v = 0)? Is it accelerating? Force? Energy change? Se
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
The study of motion in one dimension

2. Acceleration
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
Start a problem by asking 'What is the object doing?' - 'What is causing it to do that?' - What direction is it moving in (if two find x and y components)? Is it moving at constant v (this includes v = 0)? Is it accelerating? Force? Energy change? Se
Speeding up - slowing down or changing direction)

3. Velocity
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
Total distance traveled from start to finish - Is a scalar quantity (no direction)
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
The study of motion in one dimension

4. Kinematic
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
Start a problem by asking 'What is the object doing?' - 'What is causing it to do that?' - What direction is it moving in (if two find x and y components)? Is it moving at constant v (this includes v = 0)? Is it accelerating? Force? Energy change? Se
The study of motion in one dimension
Speeding up - slowing down or changing direction)

5. Key words or hints that a kinematic equation must be used
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
If acceleration is present (Question contains terms such as: starts from rest - final velocity of - accelerates - comes to rest - etc.) - then you must use the three Kinematic equations
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

6. Distance
An example of motion in 2 dimensions (both x and y simultaneously)
Speeding up - slowing down or changing direction)
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
Total distance traveled from start to finish - Is a scalar quantity (no direction)

7. Displacement
If acceleration is present (Question contains terms such as: starts from rest - final velocity of - accelerates - comes to rest - etc.) - then you must use the three Kinematic equations
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
The total distance divided by the total time for the entire trip.
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

8. Speed
The total distance divided by the total time for the entire trip.
Total distance traveled from start to finish - Is a scalar quantity (no direction)
An example of motion in 2 dimensions (both x and y simultaneously)
A scalar quantity (no direction specified) that shows the rate that distance d is covered.

9. Average speed
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
Start a problem by asking 'What is the object doing?' - 'What is causing it to do that?' - What direction is it moving in (if two find x and y components)? Is it moving at constant v (this includes v = 0)? Is it accelerating? Force? Energy change? Se
The total distance divided by the total time for the entire trip.
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

10. Instantaneous speed
Total distance traveled from start to finish - Is a scalar quantity (no direction)
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

11. The only time the average velocity equation can be used
When there is no acceleration
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
The total distance divided by the total time for the entire trip.
If acceleration is present (Question contains terms such as: starts from rest - final velocity of - accelerates - comes to rest - etc.) - then you must use the three Kinematic equations
