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

2. Speed
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
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.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.

3. 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
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
An example of motion in 2 dimensions (both x and y simultaneously)

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
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)
Speeding up - slowing down or changing direction)

5. How to calculate slope on a straight line graph
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 vector quantity consisting of magnitude and direction. Displacement x divided by time.

7. Distance
The study of motion in one dimension
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
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.

8. Kinematic
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
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 study of motion in one dimension
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.

9. Acceleration
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.
Speeding up - slowing down or changing direction)
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)

10. Average speed
When there is no acceleration
The study of motion in one dimension
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
The total distance divided by the total time for the entire trip.

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