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. Projectile Motion
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
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)

2. Distance
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
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)

3. 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
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
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

4. Instantaneous speed
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.

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

5. Displacement
Speeding up - slowing down or changing direction)
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
The study of motion in one dimension
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

6. Kinematic
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
Total distance traveled from start to finish - Is a scalar quantity (no 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

7. 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)
When there is no acceleration
The total distance divided by the total time for the entire trip.

13. Average speed
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'.)
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)

14. 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.
Total distance traveled from start to finish - Is a scalar quantity (no direction)
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
