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. Speed
A vector quantity consisting of magnitude and direction. Displacement x divided by time.
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
A scalar quantity (no direction specified) that shows the rate that distance d is covered.

2. Distance
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.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
Speeding up - slowing down or changing direction)

3. Kinematics Problem Solving Strategy

4. Projectile Motion
Shortest distance between the beginning and ending point in the problem. Is a vector quantity (has direction)
An example of motion in 2 dimensions (both x and y simultaneously)
The study of motion in one dimension
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)

5. Average speed
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
A vector quantity consisting of magnitude and direction. Displacement x divided by time.

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

7. Constant speed or velocity
If the same speed is maintained over the entire trip. Constant speed/velocity means no acceleration.
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.

8. Velocity

9. The only time the average velocity equation can be used
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.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
When there is no acceleration

10. Instantaneous speed
The speed at an instant in time. Right now. Your speedometer reading when you glance it at.
A scalar quantity (no direction specified) that shows the rate that distance d is covered.
The slope is the change in y divided by the change in x. (Otherwise known as 'the rise over the run'.)
