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

2. Constant speed or velocity
Speeding up - slowing down or changing direction)
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)

3. Kinematic
The study of motion in one dimension
When there is no acceleration
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
The total distance divided by the total time for the entire trip.

4. Distance
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
Total distance traveled from start to finish - Is a scalar quantity (no direction)
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.

5. Speed
When there is no acceleration
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.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.

6. Key words or hints that a kinematic equation must be used
An example of motion in 2 dimensions (both x and y simultaneously)
Speeding up - slowing down or changing direction)
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'.)

7. Displacement
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
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 speed at an instant in time. Right now. Your speedometer reading when you glance it at.

8. The only time the average velocity equation can be used
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
When there is no acceleration
The total distance divided by the total time for the entire trip.
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)

9. Projectile Motion
When there is no acceleration
An example of motion in 2 dimensions (both x and y simultaneously)
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
Speeding up - slowing down or changing direction)

10. Instantaneous speed
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
When there is no acceleration
Speeding up - slowing down or changing direction)
The total distance divided by the total time for the entire trip.

11. Average speed
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.
Speeding up - slowing down or changing direction)
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
