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
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.
The study of motion in one dimension
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

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

4. Displacement
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)
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
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

5. Average speed
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.
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
The study of motion in one dimension

6. The only time the average velocity equation can be used
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.
When there is no acceleration
The study of motion in one dimension

7. Acceleration
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
Speeding up - slowing down or changing direction)
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.

8. Kinematic
The study of motion in one dimension
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.
The total distance divided by the total time for the entire trip.

9. 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.
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.

10. 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
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
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.

11. Projectile Motion
Speeding up - slowing down or changing direction)
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)
When there is no acceleration

12. Instantaneous speed
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
The total distance divided by the total time for the entire trip.
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
Speeding up - slowing down or changing direction)

13. Key words or hints that a kinematic equation must be used
Total distance traveled from start to finish - Is a scalar quantity (no direction)
When there is 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
The total distance divided by the total time for the entire trip.
