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. Average speed
The total distance divided by the total time for the entire trip.
An example of motion in 2 dimensions (both x and y simultaneously)
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
A scalar quantity (no direction specified) that shows the rate that distance d is covered.

2. The only time the average velocity equation can be used
An example of motion in 2 dimensions (both x and y simultaneously)
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
When there is no acceleration
Speeding up - slowing down or changing direction)

3. Kinematic
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
Speeding up - slowing down or changing direction)
The study of motion in one dimension
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

4. Acceleration
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
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
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)

5. Distance
Total distance traveled from start to finish - Is a scalar quantity (no direction)
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)
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

6. Projectile Motion
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

7. Speed
The total distance divided by the total time for the entire trip.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
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)

8. Displacement
The study of motion in one dimension
Speeding up - slowing down or changing direction)
When there is no acceleration
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)

9. Constant speed or velocity
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
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

10. Instantaneous speed
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
An example of motion in 2 dimensions (both x and y simultaneously)
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

11. Velocity
When there is no acceleration
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.
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)

12. Key words or hints that a kinematic equation must be used
Speeding up - slowing down or changing direction)
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
Total distance traveled from start to finish - Is a scalar quantity (no direction)

13. Kinematics Problem Solving Strategy
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)
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)

14. 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'.)
