AP Physics - Kinematics Vocab

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. The only time the average velocity equation can be used
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
When there is no acceleration
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

2. How to calculate slope on a straight line graph
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
When there is no acceleration
The total distance divided by the total time for the entire trip.
An example of motion in 2 dimensions (both x and y simultaneously)

3. Key words or hints that a kinematic equation must be used
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
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
The study of motion in one dimension

4. Distance
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
When there is no acceleration
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
Total distance traveled from start to finish - Is a scalar quantity (no direction)

5. Kinematic
Total distance traveled from start to finish - Is a scalar quantity (no direction)
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
The study of motion in one dimension
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)

6. Kinematics Problem Solving Strategy
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
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
The study of motion in one dimension
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

7. Speed
Speeding up - slowing down or changing 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.
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

8. Average speed
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
Speeding up - slowing down or changing direction)
When there is no acceleration
The total distance divided by the total time for the entire trip.

9. Displacement
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
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'.)
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

10. Velocity
An example of motion in 2 dimensions (both x and y simultaneously)
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 total distance divided by the total time for the entire trip.
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

11. Instantaneous speed
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.
Speeding up - slowing down or changing direction)
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

12. Projectile Motion
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
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
An example of motion in 2 dimensions (both x and y simultaneously)
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)

13. Constant speed or velocity
Total distance traveled from start to finish - Is a scalar quantity (no direction)
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
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
