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. Kinematic
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.
Total distance traveled from start to finish - Is a scalar quantity (no direction)
The study of motion in one dimension

2. Displacement
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)
The study of motion in one dimension

3. Constant speed or 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)
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
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

4. 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
An example of motion in 2 dimensions (both x and y simultaneously)
The study of motion in one dimension
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)

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

6. Average speed
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.
The study of motion in one dimension
The total distance divided by the total time for the entire trip.

7. How to calculate slope on a straight line graph
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'.)
Speeding up - slowing down or changing direction)
When there is no acceleration

8. Velocity
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has 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
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

9. Projectile Motion
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

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

10. Instantaneous speed
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

13. The only time the average velocity equation can be used
The total distance divided by the total time for the entire trip.
When there is 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
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
